Power Electronics / Power Management
A pair of low dropout linear regulators with industrial temperature rating of –40°C to +85°C has been introduced by Diodes Incorporated.
Suiting applications including set-top boxes, routers and LCD monitors, the 300 mA, 150 mV dropout AP7335 and 600 mA, 300 mV dropout AP7365 offer adjustable and fixed output voltage operation at accuracy of 2% across the temperature range.
Input voltage is wide, at 2 V to 6 V, and both LDOs are capable of delivering an adjustable output voltage between 0,8 V and 5,0 V and fixed voltages of 0,8 V, 1,0 V, 1,2 V, 1,5 V, 1,8 V, 2,0 V, 2,5 V, 2,8 V, 3,0 V, 3,3 V and 3,9 V. Their low quiescent current of 35 μA means the devices offer power saving benefits in low-power and battery operated products. The regulators’ ability to drive low-ESR, 1 μF MLCC output capacitors helps improve stability and reduce circuit cost, while a high PSRR rating of 65 dB at 1 kHz ensures low-noise 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; the AP7365 is also available in SOT89-3L and SOT223-3L options.
