Note : 1. V
OUT
(T) = Specified Output Voltage : V
OUT
(E) = Effective Output Voltage.
2. Parameter characteristics marked with an asterisk may vary according to which type of external transistor is used.
A transistor with a value of hFE = 100 or greater and a low saturation voltage is recommended.
Unless otherwise stated, use of the following external components are recommended :
PNP Transistor, 2SA1213-Y : R
BE
, 200K
: C
L
, 10
μ
F Tantalum Capacitor.
3. The values given for ISS refer to the actual IC values ( see application circuits )
4. The IC's supply current is calculated as follows :
Supply Current = I
SS
+ ( Load Current / hFE ) + ( 0.6 / R

)

OUT
{V

V
IN1
= The Input Voltage when V
OUT
1 appears as Input Voltage is gradually decreased.
6. The Maximum Output Current value represents the value at the time the Output Voltage has decreased to V
OUT
(E) x 0.9.
Due to the limitations of Continuous Total Power Dissipation with the 2SA1213 transistor, the Maximum Output Current
Value cannot be continually achieved.
