Function: FAST-TRANSIENT-RESPONSE 1-A LOW-DROPOUT VOLTAGE REGULATOR

Package: 20-Pin TSSOP (PWP) Type

Manufacturer: Texas Instruments

Description

This device is designed to have a fast transient response and be stable with 10-µF low ESR capacitors. This combination provides high performance at a reasonable cost. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 230 mV at an output current of 1 A for the TPS76850) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over the full range of output current, 0 mA to 1 A).

These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high signal to EN(enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ= 25°C. Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator. The TPS768xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.2 V to 5.5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP package.

Part Number: APL5158

Function: 1.2 V, 150 mA, CMOS low dropout regulator with power OK

Package: SOT-23-5 pin type

Manufacturer: Anpec Electronics

Pinouts:

 

Description

The APL5158 is a precise CMOS LDO with power ok function. The APL5158 offers 2% output accuracy over temp, and an ultra low ground current 60µA.

The power good function monitors the output voltage and indicates when an error occurs in the system (active low).In the event of an output fault such as over current, thermal shutdown, the power ok output is pulled low. The APL5158 also works with low-ESR output capacitors, reducing the amount of board space for power applications, critical in hand-held wireless devices. Key features include current-limit, thermal shutdown, fast transient response.
