Microchip 3V Fixed LDO Voltage Regulator 250mA
Microchip 3V fixed LDO voltage regulator rated 250mA with 178mV dropout, 1.6µA quiescent current and SOT-23-3 surface-mount package.
Microchip 3V Fixed LDO Voltage Regulator 250mA is a CMOS low dropout positive voltage regulator that delivers a fixed 3V output at up to 250mA. It has a low input-output voltage differential of 178mV at full load, which helps maximise usable battery capacity in battery-powered designs.
Overview
The regulator combines low dropout voltage with an ultralow quiescent current of 1.6µA, reducing power consumption. It includes short-circuit and over-temperature protection to help safeguard the circuit and the device under fault conditions. Stability is maintained with a small 1.0µF ceramic output capacitor, which simplifies design and saves board space.
Key Features
- Low dropout voltage of 178mV at 250mA load
- Ultralow quiescent current of 1.6µA
- Typical output accuracy of ±0.4%
- Short-circuit and over-temperature protection
- Stable with a 1.0µF ceramic output capacitor
- Pin-compatible upgrade for older bipolar regulators and TC55 series
- Surface-mount SOT-23-3 package for space-constrained applications
Applications
This regulator is suited to battery-powered applications, where low dropout and low power consumption help extend operating life. The compact SOT-23-3 package suits space-constrained designs, and the pin-compatible footprint supports upgrades from older bipolar regulators and TC55 series designs. It is a practical choice for designers who need a fixed 3V supply from a compact package.
