CS8101
Micropower 5.0 V, 100 mA
Low Dropout Linear
Regulator with RESET
and ENABLE
The CS8101 is a precision 5.0 V micropower voltage regulator with
very low quiescent current (70 mA typ at 100 mA load). The 5.0 V
output is accurate within ±2.0% and supplies 100 mA of load current
with a typical dropout voltage of only 400 mV. Microprocessor control
logic includes an ENABLE input and an active RESET. This
combination of low quiescent current, outstanding regulator
performance and control logic makes the CS8101 ideal for any battery
operated, microprocessor controlled equipment.
The active RESET circuit includes hysteresis, and operates
correctly at an output voltage as low as 1.0 V. The RESET function is
activated during the power up sequence or during normal operation if
the output voltage drops outside the regulation limits by more than
200 mV typ. The logic level compatible ENABLE input allows the user
to put the regulator into a shutdown mode where it draws only 20 mA
typical of quiescent current.
The regulator is protected against reverse battery, short circuit, over
voltage, and thermal overload conditions. The device can withstand
load dump transients making it suitable for use in automotive
environments.
The CS8101 is functionally equivalent to the National
Semiconductor LP2951 series low current regulators.
