STMicroelectronics Voltage Regulators - Linear LF85CPT

The LF85CPT is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 8.5V with a maximum output current of 500 mA. It features a very low dropout voltage of 0.45V and operates with a low quiescent current, typically 50 µA in OFF mode and 500 µA in ON mode, making it suitable for low power and battery-powered applications. The device supports logic-controlled electronic shutdown, allowing for reduced power consumption in standby mode. Stability is achieved with only a 2.2 µF capacitor, which contributes to space and cost savings in circuit design. The LF85CPT is available in various package types, including PPAK, and operates over a temperature range of -40 to 125°C. It also offers a supply voltage rejection ratio of 80 dB (typical) and is available with output voltage tolerances of ±1% or ±2% at 25°C.
