Automotive 5V positive fixed output LDO regulator, offering 0.1A maximum output current. Features include a wide input voltage range from 6V to 28V, ±1% output voltage accuracy, and low dropout voltage (0.3V typical at 100mA). This surface-mount device is housed in a 20-pin SO Wide body with gull-wing leads, measuring 13mm x 7.6mm x 2.35mm. Integrated short circuit and thermal shutdown protection ensure robust operation across a -40°C to 150°C temperature range.
