FEATURES

DESCRIPTION

The TLV705 series of low-dropout (LDO) linear

234

•

Very Low Dropout:

regulators are low quiescent current devices with

excellent

line

and

load

transient

performance.

Designed for power-sensitive applications, a precision

bandgap and error amplifier provides typical accuracy

•

Accuracy: 0.5% Typical

of 0.5%. Low output noise, very high power-supply

•

rejection ratio (PSRR), and low dropout voltage make

•

Available in Fixed-Output Voltages from

this series of LDOs ideal for a wide selection of

0.7 V to 4.8 V

battery-operated hand-held equipment. All devices

have a thermal shutdown and current limit for safety.

•

High PSRR: 70 dB at 1 kHz

•

Stable with Effective Capacitance of 0.1

μF

Furthermore, the TLV705 is stable with an effective

output capacitance of only 0.1

μF. This feature

•

Thermal Shutdown and Overcurrent Protection

enables the use of cost-effective capacitors that have

•

Available in 0.8-mm x 0.8-mm WCSP

higher bias voltage and temperature derating. The

•

Available in Two WCSP Height Options:

devices regulate to the specified accuracy with zero

output load. The TLV705P series also provides an

– YFF: 0.625 mm Max Height

active pull-down circuit to quickly discharge output.

– YFP: 0.5 mm Max Height

The TLV705 and TLV705P series are both available

in a 0.8-mm

× 0.8-mm WCSP with two height options
