Description

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.
