TLV743P  
SBVS310C JULY 2017REVISED JUNE 2019  
TLV743P 300-mA, Low-Dropout Regulator  
1 Features  
3 Description  
The TLV743P low-dropout linear regulator (LDO) is  
an ultra-small, low quiescent current LDO that  
sources 300 mA with good line and load transient  
performance. The device provides a typical accuracy  
of 1%.  
1
Input Voltage Range: 1.4 V to 5.5 V  
Stable Operation With 1-µF Ceramic Output  
Capacitor  
Foldback Overcurrent Protection  
Packages:  
The TLV743P is designed to be stable with a small  
output capacitor with a value of 1 µF. The TLV743P  
device provides foldback current control during device  
power up and enabling. This functionality is especially  
important in battery-operated devices.  
SOT-23 (5)  
X2SON (4)  
Very Low Dropout: 125 mV at 300 mA (3.3 VOUT  
Accuracy: 1% (Typical), 1.4% (Maximum)  
Low IQ: 34 µA  
)
The TLV743P provides an active pulldown circuit to  
quickly discharge output loads when the device is  
disabled.  
Available in Fixed-Output Voltages:  
1 V to 3.3 V  
The TLV743P is available in standard DBV (SOT-23)  
and DQN (X2SON) packages.  
High PSRR: 50 dB at 1 kHz  
Active Output Discharge
