Linear & Switching Voltage Regulators

MIC94310-SYCS-TR Description

The MIC94310-SYCS-TR is a fixed output linear regulator from Microchip Technology, designed to deliver a stable 3.3V output voltage with a output maximum current of 200mA. This regulator is part of the Ripple Blocker™ series, which is known for its high performance in power management applications. The device operates with an input voltage range up to 3.6V and features a low dropout voltage of 0.1V at 200mA, making it suitable for applications where input voltage is close to the output voltage. The regulator includes an enable control feature and offers protection against over current and over temperature conditions. It is available in a 4-lead WLCSP package and is mounted using surface mount technology. Despite being marked as obsolete, the MIC94310-SYCS-TR remains a reliable choice for specific power management needs.

MIC94310-SYCS-TR Features

• Fixed Output Voltage: Delivers a stable 3.3V output, ideal for applications requiring a consistent power supply.
• Low Dropout Voltage: With a maximum dropout voltage of 0.1V at 200mA, it ensures efficient power delivery even when the input voltage is close to the output voltage.
• Enable Control Feature: Provides flexibility in power management by allowing the regulator to be enabled or disabled as needed.
• Protection Features: Over current and over temperature protection ensures the device's reliability and longevity.
