General 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 (200uA 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
● Logic Control Electronic Shutdown
● Output voltage trimmed before assembly
● -18V Reverse peak voltage
● +30V Input over voltage protection
● +60V Transient peak voltage
● Low Quiescent Current 100uA (Typ.) (On Mode)
● Internal current limitThermal shutdown protection
