The TLV771 is a small, low-dropout (LDO) linear regulator that sources 150mA of output current. This LDO provides a voltage source with high PSRR and load and line transient performance that meets the requirements for a variety of circuits. The TLV771 has a 1.4V to 5.5V input voltage range and a 0.6V to 3.3V output voltage range. This flexibility makes the device useful for multiple applications. The TLV771 features an internal soft-start circuit to avoid excessive inrush current, thus minimizing the input voltage drop during start-up. An active pulldown circuit quickly discharges the output when the LDO is disabled and provides a known start-up state. The EN input allows an external logic signal to enable or disable the regulated output. The LDO is stable with small ceramic capacitors, allowing for a small overall package size. The operating junction temperature range is from −40°C to +125°C. This LDO is available in standard SOT-23 (DBV) and 1mm × 1mm X2SON (DQN) packages.

The TLV810 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. During power-on, RESET is asserted when the supply voltage (VDD) becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDDand keeps RESET active as long as VDDremains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (low) to ensure proper system reset. The delay time (td(typ)= 200 ms) starts after VDDhas risen above the threshold voltage, VIT. When the supply voltage drops below the VITthreshold voltage, the output becomes active (high) again. No external components are required. All the devices in this family have a fixed sense-threshold voltage (VIT) set by an internal voltage divider. The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available in a 3-pin SOT-23 package.
