LP3869x/-Q1 500-mA Low-Dropout CMOS Linear Regulators
Stable With Ceramic Output Capacitors
1 Features 3 Description
The LP3869x low-dropout CMOS linear regulators

• Wide Input Voltage Range (2.7 V to 10 V)
provide tight output tolerance (2% typical), extremely

= 5 V), and excellent AC performance using
• 2% Output Accuracy (25°C)
ultralow equivalent series resistance (ESR) ceramic
output capacitors.
• Low Dropout Voltage: 250 mV at 500 mA (Typical,
5 V Out)
The low thermal resistance of the WSON, SOT-223,
and TO-252 packages allow use of the full operating
• Precision (Trimmed) Bandgap Reference
current even in high ambient temperature
• Ensured Specifications for –40°C to 125°C
environments.
• 1-µA Off-State Quiescent Current
The use of a PMOS power transistor means that no
• Thermal Overload Protection
DC base-drive current is required to bias it, thus
• Foldback Current Limiting
allowing ground pin current to remain below 100 µA
• Ground Pin Current: 55 µA (typical) at full load regardless of load current, input voltage, or operating
temperature.
• Enable Pin (LP38693)
