Microchip MCP1702 5V 250mA Low Dropout Voltage Regulator TO-92

The Microchip MCP1702 5V 250mA Low Dropout Voltage Regulator is a fixed 5V CMOS low-dropout positive voltage regulator that delivers up to 250mA of output current in a through-hole TO-92-3 package. It is designed for stable power management in battery-operated and general electronic designs.

Overview

The MCP1702 features a low quiescent current of 2 µA (typical), supporting power-efficient operation in battery-powered devices. Its input voltage range of 2.7 V to 13.2 V accommodates two to six primary cell batteries, 9 V alkaline packs, and one or two-cell Li-ion sources. A typical dropout voltage of 330 mV allows the regulator to maintain a stable 5 V output with a low input-to-output voltage differential.

Key Features

• Output voltage tolerance of ±0.4% at room temperature and ±3% maximum across the full operating temperature range
• Typical line regulation of ±0.1%
• Operating temperature range of -40 °C to +125 °C
• Stable with a wide range of output capacitors from 1 to 22 µF, including ceramic, aluminium, or tantalum types
• Integrated short-circuit and over-temperature protection to safeguard the regulator and connected circuitry

Package and Dimensions

The regulator is supplied in a through-hole TO-92-3 package, which supports straightforward prototyping and assembly. Dimensions are 3.3 (width) x 1.5 (depth) x 4.3 (height), with a weight of 0.2 g.

Choose the Microchip MCP1702 5V 250mA Low Dropout Voltage Regulator when a fixed 5V, 250mA output with low quiescent current and built-in protection features is required.
