LP38690/LP38692
1A Low Dropout CMOS Linear Regulators
Stable with Ceramic Output Capacitors
General Description
The LP38690/2 low dropout CMOS linear regulators provide
tight output tolerance (2.5% typical), extremely low dropout
voltage (450mV
lent AC performance utilizing ultra low ESR ceramic output
capacitors.
The low thermal resistance of the LLP, SOT-223 and T0-252
packages allow the full operating current to be used even in
high ambient temperature environments.
The use of a PMOS power transistor means that no DC base
drive current is required to bias it allowing ground pin current
to remain below 100 µA regardless of load current, input
voltage, or operating temperature.
Dropout Voltage: 450 mV (typ)
Ground Pin Current: 55 µA (typ) at full load.
Precision Output Voltage: 2.5% (25˚C) accuracy.
Typical Application Circuits
Note: * Minimum value required for stability.
