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
