Diodes Inc. announces LDOs that achieve 2 percent accuracy over industrial temperatures

DALLAS, USA: Diodes Inc. has introduced a pair of low dropout linear regulators with industrial temperature ratings of –40oC to +85oC. Designed for applications such as set-top boxes, routers, and LCD monitors, the 300mA, 150mV dropout AP7335 and the 600mA, 300mV dropout AP7365 offer adjustable and fixed output voltage operations at an accuracy of 2 percent 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 to 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.
