DESCRIPTION
The SM74501 ultra-low quiescent current regulator
features low dropout voltage and low current in the
standby mode. With less than 15 μA quiescent
current at a 100 μA load, the SM74501 is ideally
suited for photovoltaic and other battery operated
systems. The SM74501 retains all of the features that
are common to low dropout regulators including a low
dropout PNP pass device, short circuit protection,
reverse battery protection, and thermal shutdown.
The SM74501 has a 40V maximum operating voltage
limit, a −40°C to +125°C operating temperature
range, and ±3% output voltage tolerance over the
entire output current, input voltage, and temperature
range. The SM74501 is available in SOT–223 surface
mount package.
Typical Application
* Required if regulator is located more than 2 inches from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating
temperature range. Effective series resistance (ESR) is critical, see curve. Locate capacitor as close as possible to
the regulator output and ground pins. Capacitance may be increased without bound.
