The CAT5419 is two digital POTs integrated with control logic and 16 bytes of NVRAM memory.A separate 6-bit control register (WCR) independently controls the wiper tap position for each digital POT. Associated with each wiper control register are four 6-bit nonvolatile memory data registers (DR) used for storing up to four wiper settings. Writing to the wiper control register or any of the non-volatile data registers is via a 2-wire serial bus (I²C-like). On power-up, the contents of the first data register (DR0) for each of the two potentiometers is automatically loaded into its respective wiper control registers (WCR).The Write Protection (WP) pin protects against inadvertent programming of the data register.The CAT5419 can be used as a potentiometer or as a two terminal, variable resistor. It is intended for circuit level or system level adjustments in a wide variety of applications.

The CAT6095 is a JEDEC JC42.4 compliant Temperature Sensor designed for general purpose temperature measurements requiring a digital output.The CAT6095 measures temperature at least 10 times every second. Temperature readings can be retrieved by the host via the serial interface, and are compared to high, low and critical trigger limits stored into internal registers. Over or under limit conditions can be signaled on the open-drainEVENTpin.The CAT6095 is packaged in space saving TDFN package with exposed backside die attach pads (DAP). The exposed DAP reduces overall thermal resistance, thus providing faster response to thermal changes when compared to SOIC, TSSOP or SOT packages.

The CAT6202 is a 13 V rated 500 mA CMOS low dropout regulator that provides fast response time to load current and line voltage changes in an automotive environment.CAT6202 features a low RONP-channel pass element with internal control circuitry which prevents reverse current flow should the voltage at VOUTexceed VINas in the case of the car's battery voltage accidentally being applied to VOUT.Thermal protection and current limiting circuitry combine to protect the pass device against faults and abuse. Current limiting is user controlled through a single resistor to ground. A fault output (FLT) provides an alert should an over-current event or thermal shutdown occur.CAT6202 comes on-line gracefully even though it may be driving heavy capacitive loads thanks to built-in soft-start circuitry. Its output is protected against accidental connection to voltages greater than VINand will not conduct current backwards into its supply.CAT6202 is available in 8-pad 2 mm x 3 mm TDFN package.

The CAT6217 is a 150 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes.The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 µs.With zero shutdown current and low ground current of 55 µA typical, the CAT6217 is ideal for battery-operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.1 V typical.The CAT6217 offers 1% initial accuracy and low dropout voltage, 90 mV typical at 150 mA. Stable operation is provided with a 1 µF ceramic capacitor, reducing required board space and component cost.Other features include output short-circuit current limit and thermal protection.The device is available in the low profile (1 mm max height) 5-lead thin SOT23 package.

The CAT6218 is a 300 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes.The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 µs.With zero shutdown current and low ground current of 55 µA typical, the CAT6218 is ideal for battery-operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.1 V typical.The CAT6218 offers 1% initial accuracy and low dropout voltage, 180 mV typical at 300 mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost.Other features include fold-back current current limit and thermal protection.The device is available in the low profile (1 mm max height) 5-lead thin SOT23 package.

The CAT6220 is a 300 mA CMOS low dropout regulator whose output voltage is user adjustable that provides fast response time during load current and line voltage changes.With 1 µA of shutdown current, an internal no-load operating current of only 10 µA, and full-load operating current of 40 µA, the CAT6220 is ideal for battery-operated devices with supply voltages from 2.3 V to 6.5 V.The CAT6220 offers 1% initial accuracy and low dropout voltage, 270 mV typical at 300 mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost.Other features include current limit and thermal protection.The device is available in the low profile (1 mm max height) TSOT-23-5 and 2 mm x 2 mm TDFN-6 packages.

The CAT6241 is a low dropout CMOS voltage regulator providing up to 1000 mA of output current with fast response to load current and line voltage changes. CAT6241 offers a user adjustable output voltage from 0.5 V to 5.0 V and its low quiescent current make CAT6241 ideal for energy conscious designs. CAT6241 is available in a space saving 3 mm x 3 mm WDFN-6 package with a power pad for heat sinking to the PCB.
