1A Ultra Low Dropout Voltage Regulator
GENERAL DESCRIPTION
The TS2940 series of fixed-voltage monolithic micro-
power voltage regulators is designed for a wide range of
applications. This device excellent choice of use in
battery-power application. Furthermore, the quiescent
current increases on slightly at dropout, which prolongs
battery life. This series of fixed-voltage regulators
features low drop output voltage (Typ. 60mV at light
load and 600mV at 800mA). This includes a tight initial
tolerance of 2%, extremely good line regulation of
0.05% typ., and very low output temperature coefficient.
FEATURES
● Dropout voltage typically 0.6V @
Io=800mA
● Output current up to 1A
● Output voltage trimmed before assembly
● -18V Reverse peak voltage
● +30V Input over voltage protection
● +60V Transient peak voltage
● Internal current limit
● Thermal shutdown protection
APPLICATION
● Post Regulator for SMPS
● Industrial Instrumentation
