DIODES Incorporated Voltage Reference AP432AQL-7

The AP432AQL-7 is a 3-terminal adjustable precision shunt regulator designed for applications requiring a stable reference voltage. It offers a reference voltage of 1.24V with a tolerance of ±0.5%, and the output voltage can be set between 1.24V and 20V using external resistors. The device features a low dynamic output impedance of 0.2Ω and a sink current capability of 200mA, making it suitable for various applications where precise voltage regulation is necessary. It operates over an extended temperature range of -20°C to +85°C and has a typical temperature coefficient of 30 ppm/°C. The AP432AQL-7 is available in multiple lead-free package options, including SOT25, SC59, and SO-8, and complies with RoHS standards. However, it is noted that this part is not recommended for new designs, with a suggestion to consider the AZ431L instead.
