Texas Instruments LM2937IMPX-12
- Part Number:
- LM2937IMPX-12
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3764444-LM2937IMPX-12
- Description:
- IC REG LDO 12V 0.4A SOT223
- ECAD Model:
-
- Datasheet:
- LM2937
Description
The LM2937 is a positive voltage regulator capable of supplying up to 500 mA of load current. It utilizes a PNP power transistor to achieve a low dropout voltage characteristic, typically 0.5V at full load current. The regulator incorporates special circuitry to minimize quiescent current to 10 mA with a full load current when the input-to-output voltage differential exceeds 3V.
Features
Fully specified for operation over -40°C to 125°C
Output current exceeding 500 mA
Output trimmed for 5% tolerance under all operating conditions
Typical dropout voltage of 0.5V at full rated load current
Wide output capacitor ESR range, up to 30
Internal short circuit and thermal overload protection
Reverse battery protection
60V input transient protection
Mirror image insertion protection
Applications
The LM2937 is ideally suited for automotive applications, where it can protect itself and load circuitry from reverse battery connections, two-battery jumps, and up to 60V-50V load dump transients. It is also suitable for general-purpose voltage regulation applications.
