Plymouth chip fab Plessey has introduced a family of linear regulators with inputs from 1.7 to 12V.
Called PS22921 (0.5A, SOT23-5), PS22922 (1.0A, SOT223) and PS22924, (2.0A, SOIC-8), they are made on the firm's bipolar process.
"Many applications are demanding wider input voltages ranges for their power management to reduce the step-down regulation requirements whilst maintaining stable voltage rails down to 0.5V to power low-voltage processors and microcontroller cores," said company sales director David Owen.
There are adjustable and fixed voltage output options, and on/off control, power good with 500µs delay, a by-pass pin for lower noise, over-temperature protection and over-current protection.Operating range is -40 to 125°C junction.
