Microchip has announced a low drop-out linear regulator with 250nA quiescent current. Called MCP1811, the firm claims “faster load line and transient response when compared to other ultra-low Iq LDOs”. Looking at the data sheet (fig 2-24), Vout dips 100mV for 20µs with a 100µA to 10mA load transient (1µF X7R output cap, Vin=4.3V Vout=3.3V). Fig ...
