LP38693
- Wide Input Voltage Range (2.7 V to 10 V)
- All WSON Options are Available as AEC-Q100 Grade 1
- 2% Output Accuracy (25°C)
- Low Dropout Voltage: 250 mV at 500 mA (Typical,
5 V Out) - Precision (Trimmed) Bandgap Reference
- Ensured Specifications for –40°C to 125°C
- 1-µA Off-State Quiescent Current
- Thermal Overload Protection
- Foldback Current Limiting
- Ground Pin Current: 55 µA (typical) at full load
- Enable Pin (LP38693)
The LP3869x low-dropout CMOS linear regulators provide tight output tolerance (2% typical), extremely low dropout voltage (250 mV at 500-mA load current, VOUT = 5 V), and excellent AC performance using ultralow equivalent series resistance (ESR) ceramic output capacitors.
The low thermal resistance of the WSON, SOT-223, and TO-252 packages allow use of the full operating current 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, thus allowing ground pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.
