I'm looking for recommendations for voltage regulators for a battery powered device that needs a 5V and a 3.3V regulator.
The 5V regulator requires 500mA absolute max (powering a .5W amplifier, 5 WS2812s, and an ATTINY MCU); the 3.3V requires 30mA absolute max (a flash memory chip).
As it's battery powered I'm looking for really low quiescent current draw, that's the main concern, because the MCU will go into sleep mode but still require power from the 5V regulator. The other main concern is the drop out voltage as the battery voltage will be around 6.5V max.
Can anyone recommend good regulators for these specs?
