STMicroelectronics LD1085V36
- Part Number:
- LD1085V36
- Manufacturer:
- STMicroelectronics
- Ventron No:
- 3767422-LD1085V36
- Description:
- IC REG LDO 3.6V 3A TO220AB
- Datasheet:
- LD1085V36
Description
The LD1085 is a low drop voltage regulator capable of providing up to 3 A of output current. Dropout is guaranteed at a maximum of 1.2 V at the maximum output current, decreasing at lower loads. The LD1085 is pin-to-pin compatible with the older 3-terminal adjustable regulators, but offers better performance in terms of drop and output tolerance.
Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1085 quiescent current flows into the load, thus increasing efficiency. Only a 10 uF minimum capacitor is needed for stability.
The device is supplied in TO-220, TO-220FP, D'PAK, and D PAK/A packages. On-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25 °C.
Features
Typical dropout 1.3 V (at 3 A)
Three terminal adjustable or fixed output voltage 1.8 V, 2.5 V, 3.3 V, 5V
Guaranteed output current up to 3 A
Output tolerance ± 1% at 25 °C and ± 2% in full temperature range
Internal power and thermal limit
Wide operating temperature range -40 °C to 125°C
Package available: TO-220, TO-220FP, D PAK, D PAK/A
Pinout compatibility with standard adjustable VREG
Applications
Post regulators for switching power supplies
Power supply for microprocessor and DSP applications
Battery chargers
High efficiency linear regulators
