Document Number: DS_P0000211 1 Version: D15
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

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 1A at the maximum specified
temperature.
