1 / 20 page INPUT ADJ/GND 2 3 1 OUTPUT TLV1117LV Series www.ti.com SBVS160 – MAY 2011 1-A, Positive Fixed Voltage, Low-Dropout Regulator 1 FEATURES DESCRIPTION The TLV1117LV series of low-dropout (LDO) linear 2 • 1.5% Typical Accuracy regulators is a low input voltage version of the • Low IQ: 100 μA (max) popular 1117 voltage regulator. – 500 times lower than standard 1117 devices The TLV1117LV is an extremely low-power device • VIN: 2.0 V to 5.5 V that consumes 500 times lower quiescent current – Absolute maximum VIN = 6.0 V than traditional 1117 voltage regulators, making it suitable for applications that mandate very low • Stable with 0-mA Output Current standby current. The TLV1117LV family of LDOs is • Low Dropout: 455 mV at 1 A for VOUT = 3.3 V also stable with 0 mA of load current; there is no • High PSRR: 65 dB at 1 kHz minimum load requirement, making it an ideal choice for applications where the regulator is required to • Minimum Ensured Current Limit: 1.1 A power very small loads during standby in addition to • Stable with Cost-Effective Ceramic Capacitors: large currents on the order of 1 A during normal – With 0-Ω ESR operation. The TLV1117LV offers excellent line and load transient performance, resulting in very small • Temperature Range: –40°C to +125°C magnitude undershoots and overshoots of output • Thermal Shutdown and Ovecurrent Protection voltage when the load current requirement changes • Available in SOT223 Package from less than 1 mA to more than 500 mA. A precision bandgap and error amplifier provides APPLICATIONS 1.5% accuracy. A very high power-supply rejection • Set Top Boxes ratio enables usage of the device for post-regulation after a switching regulator. Other valuable features • TVs and Monitors include low output noise and low-dropout voltage. • PC Peripherals, Notebooks, Motherboards The device is internally compensated to be stable • Modems and Other Communication Products with 0- Ω equivalent series resistance (ESR) • Switching Power Supply Post-Regulation capacitors. These key advantages enable the use of cost-effective, small-size ceramic capacitors. Cost-effective capacitors that have higher bias voltages and temperature derating can also be used if desired. The TLV1117LV series is available in a SOT223 package. Figure 1.
