Wanted: 500uA @ 1.8V

(1/1)

NivagSwerdna:
For my latest diversion I need approx 500uA at 1.8V to power some LP5569 chips...

My initial attempt was using an AMS1117-1.8 but the output cap requirement is a bit of a pain from a cost and space point of view. I have regulated 5V to hand.

If you needed 1.8V from 5V what device would you choose?

A quick Google found TLV716/P but there are loads of other options.

Thanks in advance

Whales:
Zener-regulator style (ie parallel regulation instead of series regulation)? 1.8V diode + resistor + cap.  0.5mA is nothing.

JackJones:
I've used MCP1810 before for low current applications.

SiliconWizard:
TPS78218

if you want an alternative to TI: XC6206
