The key to this break through is the use of EEPROM registers for correction of curvature, • Enable Pin Allowing a 3µA Shutdown Mode tempco, and accuracy on a CMOS bandgap • 20mA Output Current architecture that allows package level programming • Voltage Options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, to overcome assembly shift. The shifts in voltage 4.096V accuracy and tempco during assembly of die into plastic packages limit the accuracy of references • Custom Voltage Options Available (1.8V to trimmed with laser techniques. 4.096V) Unlike other LDO references, the LM4132 is capable • VIN Range of VREF + 400mV to 5.5V @ 10mA of delivering up to 20mA and does not require an • Stable with Low ESR Ceramic Capacitors output capacitor or buffer amplifier. These • SOT23-5 Package advantages and the SOT23 packaging are important for space-critical applications. APPLICATIONS Series references provide lower power consumption • Instrumentation & Process Control than shunt references, since they do not have to idle the maximum possible load current under no load • Test Equipment conditions. This advantage, the low quiescent current • Data Acquisition Systems (60µA), and the low dropout voltage (400mV) make • Base Stations the LM4132 ideal for battery-powered solutions. • Servo Systems The LM4132 is available in five grades (A, B, C, D • Portable, Battery Powered Equipment and E) for greater flexibility. The best grade devices (A) have an initial accuracy of 0.05% with a specified • Automotive & Industrial temperature coefficient of 10ppm/°C or less, while the • Precision Regulators lowest grade parts (E) have an initial accuracy of • Battery Chargers 0.5% and a tempco of 30ppm/°C. • Communications • Medical Equipment Typical Application Circuit *Note: The capacitor CIN is required and the capacitor COUT is optional. 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.
