ideal
for
powering
Input Voltage Range:
microprocessors.
– VIN: 1.2 V to 6.0 V
The TPS740xx uses a bias input supply to allow very
– VBIAS: 2.9 V to 6.0 V
low voltage of a main input supply. The main input
Stable with Any Output Capacitance:
≥ 2.2 μF
supply operates from 1.2 V to 6.0 V and the bias
input supply requires between 3.0 V to 6.0 V for
±1% Initial Accuracy
proper operation. The TPS740xx offers adjustable
Maximum Dropout Voltage (VIN – VOUT):
output voltages down to 0.9 V.
300 mV Over Temperature
The

capacitance. A small 2.2-
μF ceramic capacitor is
Ultra-Fast Transient Response
enough for its stability.
Excellent Line and Load Regulation
The TPS740xx is available in an 8-pin power MSOP
Logic-Controlled Shutdown Option
package and a 5-pin Jr S-PAK. Its operating
temparature range is
–40°C to +125°C.
