500mA Ultra Low Dropout Voltage Regulator
DESCRIPTION
TS2937 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.) and very low drop
output voltage (Typ. 60mV at light load and 600mV at
500mA). 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=500mA
● 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

ELECTRICAL SPECIFICATIONS
Note:
1. Absolute Maximum Rating is limits beyond which damage to the device may occur.
For guaranteed specifications and test conditions see the electrical characteristics.
2. Maximum positive supply voltage of 60V must be limited duration (<100ms) and duty cycle (<1%).
3. The maximum allowable power dissipation is a function of the maximum junction temperature, T
J
, the junction
to ambient thermal resistance, R
ӨJA
, and the ambient temperature, Ta. Exceeding the maximum allowable
power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The
effective value of R
ӨJA
can be reduced by using a heatsink.
4. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
5. Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the
ground pin current and output load current.
6. Output current will decrease with increasing temperature, but it will be not dropped below 500mA at the
maximum specified temperature.
