The LT ® 1074 is a 5A (LT1076 is rated at 2A) monolithic bipolar switching regulator which requires only a few external parts for normal operation. The power switch, all oscillator and control circuitry, and all current limit components, are included on the chip.
The LT1074 and LT1076 are monolithic bipolar switching regulators from Linear Technology, offering up to 5 A (LT1074) or 2 A (LT1076) output current, a 100 kHz switching frequency, and multiple configurations such as buck, positive‑to‑negative, and boost converters.
The datasheet lists electrical characteristics including input voltage range, on‑state voltage, leakage currents, thermal resistance, and quiescent current, as well as detailed pin descriptions, package options (TO‑220, DD, plastic), and typical application circuits.
| Maximum Input Voltage | 60 V |
|---|---|
| Minimum Input Voltage (boost mode) | 5 V |
| Switching Frequency | 100 kHz |
| Quiescent Current | 8.5 mA |
| Current Limit (LT1074) | 6.5 A |
The device can operate with an input voltage up to 60 V.
Both regulators are designed for a 100 kHz switching frequency.
The boost configuration can work with input voltages as low as 5 V.
The regulators draw only 8.5 mA of quiescent current.
