NJW4184 High Voltage Very low current consumption Io=300mA Low Dropout Regulator GENERAL DESCRIPTION The NJW4184 is a high voltage and low current consumption low dropout regulator. It has two lineups as A version (built-in ON/OFF function type) and B version(3-terminal / compatible with 78L/Mseries) NJW4184 is mounted to SOT-89-3/5,TO-252-3/5 packages and corresponded to Low ESR capacitor (MLCC). The wide input range makes NJW4184 suitable for a Car accessory, industrial supplies, battery equipment and various applications. PACKAGE OUTLINE NJW4184U2 NJW4184DL3 NJW4184U3 NJW4184DL1 FEATURES • Wide Operating Voltage Range 4.0~35V(max.) • Low Current Consumption 12µA (A version.) 9µA (B version.) • Correspond to Low ESR capacitor (MLCC) • Output Current • Output Voltage Range • High Precision Output • ON/OFF function (apply only A ver.) IO(min.)=300mA VO: 2.5V to 15.0V VO ±1.0% • Internal Thermal Overload Protection • Internal Over Current Protection • Package Outline A ver. : SOT-89-5 B ver. : SOT-89-3http://www.DataSheet4U.net/ TO-252-5 TO-252-3 PRODUCT CLASSIFICATION Device Name NJW4184U2-xxA NJW4184DL3-xxA NJW4184U3-xxB NJW4184DL1-xxB Version A A B B ON/OFF Function Yes Yes - - Package SOT-89-5 TO-252-5 SOT-89-3 TO-252-3 xx=Output Voltage ex) 33=3.3V 05=5.0V PIN COFIGURATION 5 2 4 Pin Function 1.CONTROL 2.GND 3.N.C 1 2 3 4.VOUT 5.
