8 / 35 page LM10502 SNVS884B – AUGUST 2012 – REVISED MAY 2013 www.ti.com LDO Electrical Characteristics (1) (2) Unless otherwise noted, VIN = 5.0V where: VIN=VVIN = VVIN_LDO. C1 = 4.7µF,C6 = 2.2µF. The application circuit used is the one shown in "Typical Application Circuit." Limits in standard typeface are for TJ = 25°C. Limits appearing in boldface type apply over the entire operating junction temperature range of −30°C ≤ TA = TJ ≤ +85°C.

All electrical characteristics having room-temperature limits are tested during production with TJ = 25°C. All hot and cold limits are ensured by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (2) Capacitors: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics. (3) Specification ensured by design. Not tested during production. (4) Dropout voltage is the difference between the input and output at which the output voltage drops to 100mV below its nominal value.
