Taiwan Semiconductor
Document Number: DS_P0000209 1 Version: G15
500mA Ultra Low Dropout Voltage Regulator
With Inhibit Function
DESCRIPTION
The TS2938 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 very low ground current (200µA Typ.), very low
drop output voltage (Typ. 60mV at light load and 600mV
at 500mA) and output inhibit control. This includes a
tight initial tolerance of 2%, extremely good line
regulation of 0.05% typ., and very low output
temperature coefficient.
