Product Information
Product Overview
LD1085D2M25R is a 3A low-drop positive voltage regulator. It can provide up to 3A 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 10µF minimum capacitor is needed for stability. On-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25°C.
- Typical dropout 1.3V (at 3A)
- Output tolerance ±1% at 25°C and ±2% in full temperature range
- Internal power and thermal limit
- Pinout compatibility with standard adjustable VREG
- Wide operating temperature range from -40°C to 125°C
- Quiescent current is 5mA typ (VI ≤ 30V)
- Supply voltage rejection is 72dB typ (f = 120Hz, CO = 25µF, IO = 3A, VI = 7.5 ±3V)
- 2.5V output voltage
- D²PAK/A package
- Thermal regulation is 0.008%/W typ (TA = 25°C, 30ms pulse)
