6 / 28 page  LP3990 SNVS251J – MAY 2004 – REVISED SEPTEMBER 2014 www.ti.com Electrical Characteristics (1)(2) (continued) Unless otherwise noted, VEN = 950 mV, VIN = VOUT + 1 V or VIN = 2 V, whichever is higher. CIN = 1 µF, IOUT = 1 mA, COUT = 0.47 µF. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ENABLE CONTROL CHARACTERISTICS VEN = 0 V (Output is disabled) 0.001 0.1 Maximum input current TJ = 25°C IEN (8) µA at EN pin VEN = 6 V 2.5 6 10 VIN = 2 V to 6 V VIL Low input threshold VEN falling from ≥ VIH until the output is 0.4 disabled V VIN = 2 V to 6 V VIH High input threshold VEN rising from ≤ VIL until the output is 0.95 enabled (8) ENABLE Pin has 1-M Ω (typical) resistor connected to GND. 6.6 Output Capacitor, Recommended Specifications (1) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Capacitance(2) 0.7(3) 1 500 µF COUT Output capacitance ESR 5 m Ω (1) Unless otherwise specified, values and limits apply for TJ = 25°C. (2) The full operating conditions for the application should be considered when selecting a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is X7R. However, dependent on application, X5R, Y5V, and Z5U can also be used. (See Detailed Design Procedure.) (3) Limit applies over the full operating junction temperature range (TJ) of −40°C to 125°C. 6.7 Timing Requirements MIN NOM(1) MAX(2) UNIT VOUT = 0.8 V 80 150 From VEN ↑ VIH to TON Turnon time (3) VOUT 95% level VOUT = 1.5 V 105 200 µs (VIN(MIN) to 6 V) VOUT = 3.3 V 175 250 Line transient response Trise = Tfall = 30 µs (3), mV (pk- 8 16 ( ΔVOUT) ΔVIN = 600 mV pk) Transient Trise = Tfall = 1 µs (3), response Load transient response IOUT = 1 mA to 150 mA 55 100 mV ( ΔVOUT) COUT = 1 µF (1) Nom values apply for TJ = 25°C. (2) Maximum limits apply over the full operating junction temperature (TJ) range of −40°C to 125°C. (3) This electrical specification is verified by design. 6 Submit Documentation Feedback Copyright © 2004–2014, Texas Instruments Incorporated Product Folder Links: LP3990 |
