Datasheet

A pair of low dropout linear regulators with industrial temperature rating of -40 degC to +85 degC have been introduced by Diodes Incorporated. Suiting applications including set-top boxes, routers and LCD monitors, the 300mA, 150mV dropout AP7335 and 600mA, 300mV dropout AP7365 offer adjustable and fixed output voltage operation at an accuracy of 2% across the temperature range.

Input voltage is wide, at 2V to 6V, and both LDOs are capable of delivering an adjustable output voltage between 0.8V and 5.0V and fixed voltages of 0.8V, 1.0V, 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V and 3.9V. Their very low quiescent current of just 35µA means the devices offer power saving benefits in low power and battery operated products.

The regulators' ability to drive low ESR 1µF MLCC output capacitors helps improve stability and reduce circuit cost, while a high PSRR rating of 65db at 1kHz ensures low noise high quality supplies for audio and RF applications. LDO robustness is assured by integral over-current, over-temperature and short-circuit protection.

The LDOs are provided in a choice of industry standard packages and pin-outs, with both devices available in the SOT25 and DFN2020-6 outlines and the AP7365 also available in SOT89-3L and SOT223-3L options.

The 300mA AP73365 is priced from $0.14 each in 1000 piece quantities and the 600mA AP7365 from $0.17 each in 1000 piece quantities.
