Texas Instruments LP38690DTX-3.3/NOPB
- Part Number:
- LP38690DTX-3.3/NOPB
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3756952-LP38690DTX-3.3/NOPB
- Description:
- IC REG LDO 3.3V 1A TO252-3
- Datasheet:
- LP38690DTX-3.3/NOPB
Description
The LP38690 and LP38692 low-dropout CMOS linear regulators provide:
Tight output tolerance (2.5% typical)
Extremely low dropout voltage (450 mV at a 1-A load current, Vout = 5 V)
Excellent AC performance utilizing ultra-low ESR ceramic output capacitors
The low thermal resistance of the WSON, SOT-223, and TO-252 packages allows 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.
Features
Stable with ceramic output capacitors
Wide input voltage range (2.7 V to 10 V)
2.5% output accuracy (25°C)
Low dropout voltage: 450 mV at 1 A (typical, 5 VOUT)
Precision (trimmed) bandgap reference
Ensured specifications for -40°C to 125°C
1-μA off-state quiescent current
Thermal overload protection: foldback current limiting
3-lead TO-252, 5-lead SOT-223, and 6-bump WSON packages
Enable pin (LP38692)
Ground pin current: 55 μA (typical) at full load
Precision output voltage: 2.5% (25°C) accuracy
Applications
Hard disk drives
Notebook computers
Battery-powered devices
Portable instrumentation
