The CS8101 is a precision 5V
micropower voltage regulator with
very low quiescent current (70µA
typ at 100µA load). The 5V output is
accurate within ±2% and supplies
100mA of load current with a typi-
cal dropout voltage of only 400mV.
Microprocessor control logic
includes an
input and an
active
. This combination of
low quiescent current, outstanding
regulator performance and control
logic makes the CS8101 ideal for
any battery operated, microproces-
sor controlled equipment.
The active
circuit includes
hysteresis, and operates correctly at
an output voltage as low as 1V. The
function is activated during
the power up sequence or during
normal operation if the output
voltage drops outside the regulation
limits by more than 200mV typ. The
logic level compatible
input allows the user to put the reg-
ulator into a shutdown mode where
it draws only 20µA typical of quies-
cent current.
The regulator is protected against
reverse battery, short circuit, over
voltage, and thermal overload con-
ditions. The device can withstand
load dump transients making it
suitable for use in automotive envi-
ronments.
The CS8101 is functionally equiva-
lent to the National Semiconductor
LP2951 series low current regula-
tors.
