300-mA, Low-I_Q, Low-Dropout Regulator

FEATURES

DESCRIPTION

234

•

Very Low Dropout:

The TLV702xx 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 a wide

selection of battery-operated handheld equipment. All

device versions have thermal shutdown and current

limit for safety.

–

37 mV at I_OUT= 50 mA, V_OUT= 2.8 V

75 mV at I_OUT= 100 mA, V_OUT= 2.8 V

220mV at I_OUT= 300 mA, V_OUT= 2.8 V

•

2% Accuracy

•

Low I_Q: 35 μA

Fixed-Output Voltage Combinations Possible

from 1.2 V to 4.8 V

•

High PSRR: 68 dB at 1 kHz

Stable with Effective Capacitance of 0.1 μF⁽¹⁾

Thermal Shutdown and Overcurrent Protection

Packages: SOT23-5 and 1,5mm × 1,5mm SON-6

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 μF. This

feature enables the use of cost-effective capacitors

that have higher bias voltages and temperature

derating. The devices regulate to specified accuracy

with no output load.

•

(1)

See the Input and Output Capacitor Requirements in the

Application Information section.

The TLV702xxP series also provides an active

pulldown circuit to quickly discharge the outputs.
