Microchip Low Dropout Voltage Regulator 16V 150mA Surface Mount SOT-23A 3-Pin MCP1754ST-5002E/CB

Microchip MCP1754ST-5002E/CB is a high-performance low dropout linear voltage regulator designed for precision power management applications requiring up to 150 mA output current. It supports an input voltage range from 3.6 V to a maximum of 16 V, making it versatile for various automotive and industrial electronics designs.

This 3-pin SOT-23A surface mount package device offers an industry-leading power supply rejection ratio (PSRR) above 70 dB at 1 kHz, ensuring stable output voltage under noisy power conditions. The regulator features a low quiescent current of approximately 56 μA, which helps maximize battery life in portable or low-power electronics.

The MCP1754 incorporates several protection mechanisms including current foldback to limit output current during overcurrent conditions, short-circuit protection, and thermal shutdown to prevent damage under extreme operating environments. It also delivers a tight output voltage tolerance of ±0.4% typical at room temperature and ±2.0% across the full temperature range up to a maximum operating temperature of 125°C.

Its compact dimensions of 3.1 mm length, 1.8 mm width, and 1.3 mm height allow it to fit in space-constrained circuit boards, and a minimal 1 μF output capacitor ensures stable operation without large capacitance requirements.

The device meets the stringent AEC-Q100 automotive standard, making it suitable for automotive power management applications requiring reliability and durability in harsh environments.

Operates with input voltage from 3.6 V to 16 V for flexible power supply options. Output current capacity of 150 mA for moderate load power delivery. High PSRR (>70 dB at 1 kHz) for enhanced noise rejection in sensitive circuits.

Low quiescent current of 56 μA optimizes battery-operated device efficiency. Includes current foldback, short-circuit and over-temperature protection for device safety. Compact 3-pin SOT-23A surface mount package for easy PCB integration.

Certified to automotive AEC-Q100 for use in vehicles and demanding industrial systems. Small required output capacitance (1 μF) enables compact power supply designs.

This voltage regulator is ideal for applications in industrial electronics, automotive power supplies, portable battery-operated devices, consumer electronics, and embedded systems requiring reliable, efficient, and compact voltage regulation solutions.
