(Note 1)
V_IN = V_OUT – 0.2 V; I_OUT = 250 mA
V_IN = V_OUT +1.5 V to V_IN = V_OUT +2.5 V;
I_OUT = 250 mA
I_OUT = 0 to 250 mA
T_j = –30 to +85 °C
RR
Ripple rejection (Note 1)
f = 120 Hz; V_ripple = 1 V; I_OUT = 250 mA
V_n
Output noise voltage (Note 1)
f_BW = 20 to 80 kHz; C_n = 470 pF
I_ON/OFF
ON/OFF pin input current
V_ON/OFF = V_IN
V_ON/OFF(H) ON/OFF HIGH threshold voltage
V_ON/OFF(L) ON/OFF LOW threshold voltage
NOTES:
1. The parameter is guaranteed by design.
2. This parameter is not guaranteed if V_OUT is less than 2 V.
