5 / 21 page LP5907 www.ti.com SNVS798D – APRIL 2012 – REVISED NOVEMBER 2012 ELECTRICAL CHARACTERISTICS (1)(2)(3) (continued) Limits in standard typeface are for TA = 25°C. Limits in boldface type apply over the full operating junction temperature range (–40°C ≤ TJ ≤ +125°C). Unless otherwise noted, specifications apply to LP5907 (all packages) Typical Application Circuit (pg. 1) with: VIN = VOUT (NOM) + 1 V, VEN = 1.2 V, CIN = 1 µF, COUT = 1 µF, IOUT = 1 mA. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TRANSIENT CHARACTERISTICS VIN = (VOUT(NOM) + 1 V) to (VOUT(NOM) + 1.6 V) –1 in 30 µs, IOUT = 1 mA Line transient(11) mV VIN = (VOUT(NOM) + 1.6 V) to (VOUT(NOM) + 1 V) 1 in 30 µs, IOUT = 1 mA ΔVOUT IOUT = 1mA to 200 mA in 10 µs –40 Load transient(11) mV IOUT = 200 mA to 1mA in 10 µs 40 Overshoot on startup(11) Stated as a percentage of nominal VOUT 5 % Turn-on time To 95% of VOUT(NOM) 80 150 µs (11) This specification is ensured by design. OUTPUT AND INPUT CAPACITORS over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN(1) TYP MAX UNIT CIN Input capacitance(2) 0.7 1 Capacitance for stability µF COUT Output capacitance(2) 0.7 1 10 ESR Output/Input capacitance(2) 5 500 m Ω (1) Note: The minimum capacitance should be greater than 0.5 μF over the full range of operating conditions. The capacitor tolerance should be 30% or better over the full temperature range. The full range of operating conditions for the capacitor in the application should be considered during device selection to ensure this minimum capacitance specification is met. X7R capacitors are recommended however capacitor types X5R, Y5V and Z5U may be used with consideration of the application and conditions. (2) This specification is guaranteed by design.
