Hello,

I cannot agree to the last statement.
It mainly depends if you use LTZ1000 or LTZ1000A and temperature 
setpoint and thermal isolation.

Just for comparison:
My two LTZ1000A with 50 deg C setpoint are using 20-21 mA each at 23 deg 
C and 14V stabilized supply (from 12 NiMH cells = 15V battery)
My LM399#3 uses 30mA at room temp and 9.35V stabilized supply (from 8 
NiMH cells = 10V battery)

so total power is around 300mW in both cases.

with best regards

Andreas
