LP38690-ADJ/LP38692-ADJ
1A Low Dropout CMOS Linear Regulators with
Adjustable Output
Stable with Ceramic Output Capacitors
General Description
The LP38690/2-ADJ low dropout CMOS linear regulators
provide 2.5% precision reference voltage, extremely low
dropout voltage (450mV
@
1A load current, V
= 5V) and
excellent AC performance utilizing ultra low ESR ceramic
output capacitors.
The low thermal resistance of the LLP and SOT-223 pack-
ages 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)
@
1A (typ. 5V out).
Ground Pin Current:
55 μA (typ) at full load.
Adjust Pin Voltage:
2.5% (25C) accuracy.
