When the operating junction temperature rises over 150°C, the internal circuit shuts down the output voltage. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded. TYPICAL CONNECTION D 12 D 11 OUTPUT1 µ PC37M31, 37M32 INPUT CIN OUTPUT2 + + COUT1 COUT2 D21 D22 CIN: 0.1 µF or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure to connect CIN to prevent parasitic oscillation. Use of a film capacitor or other capacitor with excellent voltage and temperature characteristics is recommended. If using a laminated ceramic capacitor, it is necessary to ensure that CIN is 0.1 µF or higher for the voltage and temperature range to be used. COUT1, COUT2: 10 µF or higher. Be sure to connect COUT1 and COUT2 to prevent oscillation and improve excessive load regulation. Place CIN, COUT1 and COUT2 as close as possible to the IC pins (within 2 cm). Also, use an electrolytic capacitor with low impedance characteristics if considering use at sub-zero temperatures. D11, D12: If the OUTPUT1 pin or OUTPUT2 pin has a higher voltage than the INPUT pin, connect a diode. D21, D22: If the OUTPUT1 pin or OUTPUT2 pin has a lower voltage than the GND pin, connect a Schottky barrier diode. Caution Make sure that no voltage is applied to the OUTPUT1 pin or OUTPUT2 pin from external. 2 Data Sheet G16444EJ1V0DS µPC37M31,37M32 RECOMMENDED OPERATING CONDITIONS Parameter Symbol MIN. TYP.

Data Sheet G16444EJ1V0DS 9 µPC37M31,37M32 CAUTION ON USE When the µ PC37M31 and 37M32 are used with an input voltage that is lower than the value indicated in the recommended operating conditions, a large quiescent current flows through the device due to saturation of the transistor of the output stage. (Refer to the IBIAS (IBIAS (S)) vs. VIN curves in TYPICAL CHARACTERISTICS). These products have saturation protector, but a current of up to 70 mA MAX. may flow through the device. Thus, the power supply on the input side must have sufficient capacity to allow this quiescent current to pass when the device starts up.
