PQ05RR1

PQ05RR1 Description

The PQ05RR1 is a linear voltage regulator designed and manufactured by Sharp Microelectronics. This device provides a fixed output voltage of 5V with a maximum output current of 1A. It is housed in a TO220-4 package, making it suitable for through-hole mounting. The PQ05RR1 is designed to operate with an input voltage range up to 35V, ensuring compatibility with a wide range of power supply sources. This regulator features a quiescent current of 10 mA, which helps in minimizing power consumption during operation. Additionally, it offers a Power Supply Rejection Ratio (PSRR) of 55dB at 120Hz, ensuring stable output voltage even under varying input conditions. The device includes protection features such as over-current and over-temperature protection, enhancing its reliability and longevity. The PQ05RR1 also includes a reset control feature, providing additional flexibility in system design. Despite its robust features, the PQ05RR1 is now considered obsolete, which may impact its availability in the market.
