STL6340
250mA Low Quiescent Current Linear Regulator
■DESCRIPTION
■FEATURE
The STL6340 series is a positive voltage
regulator with high accuracy output voltage and
ultra-low quiescent current which is typically 2.0μA.
The device is ideal for handheld communication
equipments and battery powered applications which
require low quiescent current.
The STL6340 consists of a bandgap reference
voltage source, an error amplifier, a P-channel pass
transistor, a resistor-divider for setting output
voltage, a current limiter, and temperature limit
protection circuit. The high-accuracy output voltage
is preset at an internally trimmed voltage 1.8V, 2.5V
or 3.3V. Other output voltages can be
maskoptioned from 1.2V to 5.0V with 100mV
increment. (but only 1.28V in stead of 1.3V)
Low Current Consumption: 2μA
Short Circuit Protection: 200mA
