WL9015
WL9015 is 500mA Low-Dropout LDO manufactured by wpmtek.
Description
The WL9015 series are high accuracy, CMOS LDO Voltage Regulators, offering Low Power Consumption, high ripple rejection ratio and low dropout.Internally. The WL9015 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase pensators. The WL9015 ’s current limiters' foldback circuit also operates as a short protect for the output current limiter and the output pin. The WL9015 series is also fully patible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption,ideal for powering the battery equipment to a longer service life.
