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.

Figure 3. Typical Circuit Waveforms for Output
Stage Protection
If the input voltage rises above 30 V (e.g. load dump), the
output shuts down. This response protects the internal
circuitry and enables the IC to survive unexpected voltage
transients.
Should the junction temperature of the power device
exceed 180°C (typ) the load current capability is reduced
thereby preventing thermal overload. This thermal
management function is an effective means to prevent die
overheating since the load current is the principle heat
source in the IC.
REGULATOR CONTROL FUNCTIONS
The CS8101 contains two microprocessor compatible
control functions: ENABLE and RESET (Figure 4).

ENABLE Function
The ENABLE function switches the output transistor ON
and OFF. When the voltage on the ENABLE lead exceeds
1.4 V typ, the output pass transistor turns off, leaving a high
impedance facing the load. The IC will remain in Sleep
mode, drawing only 50 mA, until the voltage on this input
drops below the ENABLE threshold.
RESET Function
A RESET signal (low voltage) is generated as the IC
powers up until VOUT is within 250 mV of the regulated
output voltage, or when VOUT drops out of regulation, and
is lower than 300 mV below the regulated output voltage. A
hysteresis of 50 mV is included in the function to minimize
oscillations.
