MaxLinear, Inc. Voltage Regulators - Linear SPX431LAM-L

The SPX431LAM-L is a precision adjustable shunt voltage regulator from Quarktwin Technology Ltd., featuring a tight voltage tolerance of 0.5% at 10mA and a wide operating current range from 1mA to 100mA. It operates effectively within an extended temperature range of 0°C to 105°C and has a low temperature coefficient of 30 ppm/°C. This device serves as an improved replacement for TL431 and AS431 regulators, providing a cost-effective solution for various applications, including battery-operated equipment, adjustable supplies, and switching power supplies. The output voltage can be adjusted between the reference voltage of 2.503V and 20V using two external resistors. The SPX431LAM-L is available in a 3-pin SOT-23 package and is designed for high thermal stability, making it suitable for applications that require reliable performance. The device also features low off-state leakage and dynamic output impedance, contributing to its efficiency in power regulation tasks.
