SULR1190 Technical Data Data Sheet N1577, Rev. - Ultra LDO 1A Linear Regulator With Description: A low noise, high PSRR and ultra low dropout linear regulator SULR1190 is optimized for low ESR ceramic capacitors operation with 1A continuous current. The SULR1190 offers high precision output voltage of ±2% tolerance. Output voltage can also be adjusted for those other than the preset values. A noise bypass pin is available for further reduction of output noise. The bypass pin could be floating if it’s unnecessary. At 1A load current and 2.8V output voltage, a 440mV dropout is performed. The quality of low quiescent current and low dropout voltage makes this device ideal for battery power applications. The high ripple rejection and low noise of the SULR1190 provide enhanced performances for critical applications such as cellular phones, and PDAs. In addition, a logic-level shutdown input is included, which reduce supply current to less than 0.1μA (typ.) in shutdown mode with fast turn-on time less than 100μs. The SULR1190’s current limit and thermal protection provide protection against any overload condition that would create excessive junction temperatures.

The device is available in an adjustable version and fixed output voltages ranging from 1.2V to 3.8V, and the device can supply loads up to 1A. SHUTDOWN __ By connecting EN(EN) pin to VIN(ground), the SULR1190 can be shut down to reduce the supply current to 0.1μA(typ.). At this operation mode, the output voltage of SULR1190 is equal to 0V. CURRENT LIMIT The SULR1190 includes a current limiter, which monitors and controls the maximum output current. If the output is overloaded or shorted to ground, this can protect the device from being damaged. THERMAL PROTECTION The SULR1190 includes a thermal-limiting circuit, which is designed to protect the device against overload condition. When the junction temperature exceeds TJ=150ºC, the thermal-limiting circuit turns off the pass transistor and allows the IC to cool. For continuous load condition, maximum rating of junction temperature must not be exceeded. INPUT-OUTPUT CAPACITORS Linear regulators require input and output capacitors to maintain stability. Input capacitor at 2.2μF with a 2.2μF ceramic output capacitor is recommended. When choosing the input and output ceramic capacitors, X5R and X7R types are recommended because they retain their capacitance over wider ranges of voltage and temperature than other types. NOISE BYPASS CAPACITOR A 22nF bypass capacitor at BP pin can reduce output voltage noise. The bypass pin can be floating if it’s unnecessary. OUTPUT VOLTAGE PROGRAMMING The output voltage of SULR1190 linear regulator can be set by its internal feedback resistors when the ADJ pin is grounded. In addition, the output voltage of SULR1190 linear regulator can be set by the external feedback resistors when connecting a resistive divider R1 and R2. While connecting a resistive divider, VOUT can be calculated as: R1 VOUT = 0.8×{1+ } R2 The resistive divider should sit as close to ADJ pin as possible. POWER DISSIPATION The maximum power dissipation of SULR1190 depends on the thermal resistance of its case and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The rate of temperature rise is greatly affected by the mounting pad configuration on the PCB, the board material, and the ambient temperature. When the IC mounting with good thermal conductivity is used, the junction temperature will be low even when large power dissipation applies. The power dissipation across the device is P = I OUT (V -V IN OUT ). • China - Germany - Korea - Singapore - United States • • http://www.smc-diodes.com - sales@ smc-diodes.com • SULR1190 Technical Data Data Sheet N1577, Rev. - Ultra LDO 1A Linear Regulator With The maximum power dissipation is: (TJ-max - TA) PMAX = RΘJA is the maximum allowable junction temperature (150°C), and T is the ambient temperature Where T J-max A suitable in application. As a general rule, the lower temperature is, the better reliability of the device is. So the PCB mounting pad should provide maximum thermal conductivity to maintain low device temperature. • China - Germany - Korea - Singapore - United States • • http://www.smc-diodes.com - sales@ smc-diodes.com • SULR1190 Technical Data Data Sheet N1577, Rev. - Ultra LDO 1A Linear Regulator With Physical Dimensions TO-220 (unit: mm) Note: 1.
