Regulator block Table 10 (VIN = 13.5 V, Tj = −40°C to +150°C unless otherwise specified) Item Symbol Condition Min. Typ. Max. Unit Test Circuit Output voltage*1 VOUT(E) VIN = 13.5 V, IOUT = 30 mA VOUT(S) − 2.0% VOUT(S) VOUT(S) + 2.0% V 1 Output current*2 IOUT VIN ≥ VOUT(S) + 1.0 V 200*4 − − mA 2 Dropout voltage*3 Vdrop IOUT = 30 mA, Ta = +25°C, VOUT(S) = 3.0 V to 5.3 V − 40 50 mV 1 IOUT = 100 mA, Ta = +25°C, VOUT(S) = 3.0 V to 5.3 V − 120 200 mV 1 Line regulation ΔVOUT1 ΔVIN • VOUT VOUT(S) + 1.0 V ≤ VIN ≤ 36.0 V, IOUT = 30 mA, Ta = +25°C − 0.02 0.10 %/V 1 Load regulation ΔVOUT2 VIN = 13.5 V, 100 μA ≤ IOUT ≤ 100 mA, Ta = +25°C − 20 40 mV 1 Input voltage VIN − 4.0 − 36.0 V − Ripple rejection |RR| VIN = 13.5 V, IOUT = 30 mA, f = 100 Hz, ΔVrip = 1.0 Vp-p − 70 − dB 3 Short-circuit current Ishort VIN = 13.5 V, VOUT = 0 V, Ta = +25°C − 60 − mA 2 Thermal shutdown detection temperature TSD Junction temperature − 170 − °C − Thermal shutdown release temperature TSR Junction temperature − 135 − °C − *1. VOUT(S): Set output voltage VOUT(E): Actual output voltage Output voltage when fixing IOUT (= 30 mA) and inputting 13.5 V *2. The output current at which the output voltage becomes 95% of VOUT(E) after gradually increasing the output current. *3. Vdrop = VIN1 − (VOUT3 × 0.98) VOUT3 is the output voltage when VIN = VOUT(S) + 1.0 V. VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input voltage. *4. The output current can be at least this value. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power dissipation when the output current is large. This specification is guaranteed by design. |
