NCV4299C Voltage Regulator - Low-Dropout 150 mA The NCV4299C is a family of precision micropower voltage www.onsemi.com regulators with an output current capability of 150 mA. It is available in 5.0 V or 3.3 V output voltage. MARKING The output voltage is accurate within 2% with a maximum dropout DIAGRAMS voltage of 0.5 V at 100 mA. Low Quiescent current is a feature 8 drawing only 80 A with a 100 A load. This part is ideal for any and SO8 299Cx all battery operated microprocessor equipment. 8 D1 SUFFIX ALYW The device features microprocessor interfaces including an CASE 751 1 1 adjustable reset output and adjustable system monitor to provide shutdown early warning. An inhibit function is available. With inhibit 14 active, the regulator turns off and the device consumes less than 1.0 A of quiescent current. SO14 V4299CxxG 14 D2 SUFFIX The part can withstand load dump transients making it suitable for AWLYWW CASE 751A use in automotive environments. 1 1 Features 5.0 V, 3.3 V 2%, 150 mA x, xx = 3 or 33 (3.3 V Version) Extremely Low Current Consumption = 5 or 50 (5.0 V Version) 80 A (Typ) in the ON Mode A = Assembly Location WL, L = Wafer Lot 1.0 A in the Off Mode Y = Year Early Warning WW, W = Work Week Reset Output Low Down to V = 1.0 V G or = PbFree Package Q (Note: Microdot may be in either location) Adjustable Reset Threshold Wide Temperature Range Fault Protection PIN CONNECTIONS 60 V Peak Transient Voltage 40 V Reverse Voltage 114 RADJ SI Short Circuit D I 1 8 Thermal Overload I Q GND GND Internally Fused Leads on SO14 Package SI SO GND GND RO RADJ Inhibit Function with 1 A Current Consumption in the Off Mode GND GND GND D INH Q AECQ100 Grade 1 Qualified and PPAP Capable SOIC8 RO SO These are PbFree Devices SOIC14 ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 17 of this data sheet.

SO8 Simplified Block Diagram PIN FUNCTION DESCRIPTION SO8 PACKAGE Pin Symbol Description 1 I Input. Battery Supply Input Voltage. Bypass directly to GND with ceramic capacitor. 2 SI Sense Input. Can provide an early warning signal of an impending reset condition when used with SO. Connect to Q if not used. 3 RADJ Reset Adjust. Use resistor divider to Q to adjust reset threshold lower. Connect to GND if not used. 4 D Reset Delay. Connect external capacitor to ground to set delay time. 5 GND Ground. 6 RO Reset Output. NPN collector output with internal 20 k pullup to Q. Notifies user of out of regulation condition. Leave open if not used. 7 SO Sense Output. NPN collector output with internal 20 k pullup to Q. Can be used to provide early warning of an impending reset condition. Leave open if not used. 8 Q 5.0 V, 3.3 V, 2%, 150 mA output. Use 22 F, ESR 4 to ground. www.onsemi.com 2
