NJM2390U-TE1

NJM2380/A, NJM2390/A ADJUSTABLE HIGH PRECISION SHUNT REGULATOR ■ GENERAL DESCRIPTION The NJM2380/A and NJM2390/A are adjustable high precision shunt regulators. They are adapted for downsizing power supply module, battery charger and others, because an ultra mini package SOT23-5 is included in the package line-up. ■ PACKAGE OUTLINE ■ FEATURES ● Operating Voltage VREF to 18V ● High Precision Voltage Reference 2.465V±2% 2.465V±1% : A Version ● Mounted in Ultra Mini Package SOT23-5 ● Minimum External Parts ● Bipolar Technology ● Package Outline DMP8, SOP8 JEDEC 150mil SOT89-3, SOT23-5 NJM2380M/AM ( DMP8 ) NJM2380E/AE ( SOP8 ) NJM2380U/AU NJM2390U/AU ( SOT89-3 ) NJM2380F/AF ( SOT23-5 ) ■ PIN CONFIGURATION PIN FUNCTION NJM2380M/AM NJM2380E/AE 1. 2. 3. 4. 5. 6. 7. 8.
