Part Number: TLV70012

Function: 200-mA, Low IQ, Low-Dropout Regulators for Portable Devices

Package: SC70-5, SOT-5, WSON-6 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The TLV70012, TLV700xx series of low-dropout (LDO) linear regulators are low quiescent current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications. A precision bandgap and error amplifier provides overall 2% accuracy. Low output noise, very high power-supply rejection ratio (PSRR), and low dropout voltage make this series of devices ideal for most battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.

The TLV700xx series of LDOs are available in 1,5-mm × 1,5-mm SON-6, TSOT23-5, and SC-70 packages.

Features

1. Very Low Dropout:
(1) 43 mV at IOUT = 50 mA, VOUT = 2.8 V
(2) 85 mV at IOUT = 100 mA, VOUT = 2.8 V
(3) 175 mV at IOUT = 200 mA, VOUT = 2.35 V

2. 2% Accuracy
3. Low IQ: 31 µA
4. Available in Fixed-Output Voltages from 1.2 V to 4.8 V
5. High PSRR: 68 dB at 1 kHz
6. Stable with Effective Capacitance of 0.1 µF(1)
7.. Thermal Shutdown and Overcurrent Protection

Description

The TL431AIP, TL431 and TL432 devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors.

These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
