www.ti.com SBVS150A – SEPTEMBER 2010 – REVISED JANUARY 2011 300-mA, Sub-Bandgap Output Voltage, Low-IQ, Low-Dropout Regulator
FEATURES DESCRIPTION 2% Accuracy Low IQ: 35 mA Fixed-Output Voltage Combinations Possible
from 0.7 V to 1.15 V(1) High PSRR: 68 dB at 1 kHz Stable with Effective Capacitance of 0.1 mF(2) Thermal Shutdown and Overcurrent Protection Packages: SOT23-5, 1,5-mm Г— 1,5-mm SON-6 The TLV712xx series of low-dropout linear regulators
(LDOs) are low quiescent current devices with
excellent line and load transient performance. These
devices provide sub-bandgap output voltages; that is,
output voltages less than 1.2 V all the way down to
0.7 V. Therefore, these LDOs can be used to power
processors with operating voltages less than 1.2 V.
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. 1 234 (1) For output voltage of 1.2 V and higher, see the TLV702 family
