MIC39151-1.65WU by Microchip Technology

The MIC39151-1.65WU is a high-performance, adjustable voltage regulator designed by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This regulator is part of the MIC39150 series and is specifically engineered to deliver a continuous output current of up to 1.5A with an input voltage range of 2.25V to 6V, making it ideal for a wide variety of applications in the consumer, automotive, and industrial markets.

Featuring a low dropout voltage (LDO) of typically 1.3V at full load, the MIC39151-1.65WU ensures efficient operation even in applications where the input voltage is very close to the output voltage. This is particularly beneficial in battery-operated devices where maximizing the usage of available power is crucial.

With an adjustable output voltage range from 1.65V to as low as 1.24V, this regulator provides the flexibility needed to cater to different system requirements. This is achieved through an external resistor divider, allowing designers to set the output voltage to the desired level accurately.

The MIC39151-1.65WU incorporates several protective features to ensure the longevity and reliability of the end application. These include over-temperature protection, current-limit protection, and a thermal shutdown mechanism that safeguards the device and the system under extreme operating conditions. Furthermore, the regulator offers a fast transient response and excellent line and load regulation, which contribute to the stable operation of the system it powers.

This voltage regulator comes in a fixed 5-pin TO-263 (D2PAK) surface-mount package, which is known for its thermal efficiency and compact footprint. The package is designed to optimize the thermal performance, making it an excellent choice for space-constrained applications that require efficient heat dissipation.

Whether you are designing power supplies for portable electronics, computer peripherals, or automotive electronics, the MIC39151-1.65WU from Microchip Technology is a reliable and versatile solution that provides precision, efficiency, and durability.
