TLV740P 300-mA, Low-Dropout Regulator
With Foldback Current Limit
1 Features
3 Description
•
•
Foldback overcurrent protection
Packages:
– 1-mm × 1-mm, 4-pin X2SON
– 5-pin SOT-23
Very low dropout: 460 mV at 300 mA
Accuracy: 1%
The TLV740P low-dropout (LDO) linear regulator is a
low quiescent current LDO with excellent line and load
transient performance designed for power-sensitive
applications. This device provides a typical accuracy
of 1%.

The TLV740P also provides inrush current control
during device power up and enabling. The TLV740P
limits the input current to the defined current limit to
avoid large currents from flowing from the input power
source. This functionality is especially important in
battery-operated devices.
Low IQ: 50 µA
Input voltage range: 1.4 V to 5.5 V
Available in fixed-output voltages:
1 V to 3.3 V
High PSRR: 65 dB at 1 kHz
Active output discharge

•
The TLV740P is available in standard DQN and DBV
packages. The TLV740P also provides an active
pulldown circuit to quickly discharge output loads.
