The LM4128’s advanced • Low Supply Current, 60 µA design eliminates the need for an external stabilizing capacitor while ensuring stability with capacitive loads • Enable Pin Allowing a 3 µA Shutdown Mode up to 10 µF, thus making the LM4128 easy to use. • Up to 20 mA Output Current Series references provide lower power consumption • Voltage Options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, than shunt references, since they do not have to idle 4.096V the maximum possible load current under no load • Custom Voltage Options Available (1.8V to conditions. This advantage, the low quiescent current 4.096V) (60 µA), and the low dropout voltage (400 mV) make the LM4128 ideal for battery-powered solutions. • VIN Range of VREF + 400 mV to 5.5V @10 mA • Stable with Low ESR Ceramic Capacitors The LM4128 is available in four grades (A, B, C, and D) for greater flexibility. The best grade devices (A) • 5-Pin SOT-23 Package have an initial accuracy of 0.1% with ensured • −40°C to 125°C Junction Temperature Range temperature coefficient of 75 ppm/°C or less, while • LM4128AQ/BQ/CQ/DQ are AEC-Q100 Grade 1 the lowest grade parts (D) have an initial accuracy of Qualified and are Manufactured on an 1.0% and a tempco of 100 ppm/°C. Automotive Grade Flow Typical Application Circuit APPLICATIONS • Instrumentation & Process Control • Test Equipment • Data Acquisition Systems • Base Stations • Servo Systems • Portable, Battery Powered Equipment • Automotive & Industrial Electronics • Precision Regulators *Note: The capacitor CIN is required and • Battery Chargers the capacitor COUT is optional. • Communications • Medical Equipment 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
