Microchip Technology, Inc. Voltage Regulators - Linear MIC94345-4YCS TR

The MIC94345-4YCS TR is a linear voltage regulator designed for applications requiring low-frequency ripple attenuation. It operates within an input voltage range of 1.8V to 3.6V and provides a fixed output voltage of 1.2V with a maximum output current of 500mA. This device features high power supply ripple rejection (PSRR) of over 50dB from 10Hz to 5MHz, making it suitable for sensitive applications such as RF circuits. The MIC94345-4YCS TR is packaged in a compact 0.84mm x 1.32mm 6-ball chip-scale package (CSP), which is beneficial for space-constrained designs. It includes a logic-controlled enable pin for ON/OFF control and is protected against current and thermal limits. The operating temperature range is from -40¬8C to +125¬8C, allowing for use in various environments. This product is ideal for applications in smartphones, tablets, digital cameras, and automotive systems where low noise and efficient power management are critical.
