Note : 1. VOUT(T) = Specified Output Voltage : VOUT(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 : RBE, 200K Ω : CL, 10 µF 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 = ISS + ( Load Current / hFE ) + ( 0.6 / RBE )
5. VDIF = { VIN1 - VOUT1 }
VOUT1 = A voltage equal to 98% of the Output Voltage whenever an amply stabilised IOUT {VOUT(T)+1.0V} is input.
VIN1 = The Input Voltage when VOUT1 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 VOUT (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.
