Taiwan Semiconductor
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.
FEATURES
● Dropout voltage typically 0.5V @Io=500mA
● Output current up to 500mA

● -18V Reverse peak voltage
● +30V Input over voltage protection
● +60V Transient peak voltage
● Low Quiescent Current 100µA (Typ.) (On Mode)
● Internal current limit
● Thermal shutdown protection
APPLICATION
● Telecommunication
