STMicroelectronics LF25ABDT
- Part Number:
- LF25ABDT
- Manufacturer:
- STMicroelectronics
- Ventron No:
- 3767454-LF25ABDT
- Description:
- IC REG LDO 2.5V 0.5A DPAK
- Datasheet:
- LF00 Series Datasheet
Description
The LF00 series are very low drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK, and PPAK packages and in a wide range of output voltages. The very low drop voltage (0.45V) and the very low quiescent current make them particularly suitable for low noise, low power applications and especially in battery-powered systems.
In the 5-pin configuration (PENTAWATT and PPAK), a shutdown logic control function is available (pin 2, TTL compatible). This means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. In the three-terminal configuration, the device has the same electrical performance but is fixed in the ON state. It requires only a 2.2 uF capacitor for stability, allowing space and cost saving.
Features
Very low dropout voltage (0.45V)
Very low quiescent current (TYP. 50 μA in OFF mode, 500 μA in ON mode)
Output current up to 500 mA
Logic-controlled electronic shutdown
Output voltages of 1.5; 1.8; 2.5; 2.7; 3; 3.3; 3.5; 4; 5; 6; 8; 8.5; 9; 12V
Internal current and thermal limit
Only 2.2 μF for stability
Available in ±1% (AB) or ±2% (C) selection at 25°C
Supply voltage rejection: 80db (typ.)
Temperature range: -40 to 125°C
Applications
Battery-powered systems
Low noise, low power applications
Local regulators
Standby power supplies
