DESCRIPTION

FEATURES

■ Adjustable Output Down To 1.25V ■ 1% Output Accuracy ■ Output Current of 1.5A ■ Low Dropout Voltage of 390mV @ 1.5A ■ Extremely Tight Load and Line Regulation ■ Extremely Fast Transient Response ■ Reverse-Battery Protection ■ Zero Current Shutdown (5 pin version) ■ Error Flag Signal Output for Out of Regulation State (5 pin version) ■ Standard TO-220 and TO-263 Packages The SPX29150/51/52/53 are 1.5A, highly accuracy voltage regulators with a low drop out voltage of 390mV dropout (typical) @ 1.5A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against over-current, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features in the 5 pin versions include Enable, and Error Flag. The SPX29150/51/52/53 is offered in 3 & 5-pin TO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.

Note 2: V Note 3: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current to the ground current. Note 4: Thermal regulation is defined as the change in the output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Note 5: Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured 6V input. To express these thresholds in terms of output voltage change, multiply the error amplifier gain = VOUT /VREF = (R1 + R2)/R2. For example, at a programmable output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95mVx 5V/ 1.240V = 38mV. Threshold remain constant as a percent of V OUT as VOUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed. Note 6: VEN ≤ 0.8V and VIN ≤ 16V, VOUT = 0. Note 7: Maximum positive supply voltage of 20V must be of limited duration (<100m_) < 1%. The maximum continuous supply voltage is 16V.

Date:5/25/04 SP29150/51/52/53 1.5A Low Dropout Voltage Regulator © Copyright 2004 Sipex Corporation The SPX29150/51/52/53 incorporates protec- tion against over-current faults, reversed load insertion, over temperature operation, and positive and negative transient voltage. Thermal Considerations Although the SPX29150/51/52/53 offers limiting circuitry for overload conditions, it is still necessary to insure that the maximum junction temperature is not exceeded in the application. Heat will flow through the lowest resistance path, the junction-to-case path. In order to insure the best thermal flow of the component, proper mounting is required. Consult the heatsink manufacturer for thermal resistance and heat sink design. TO-220 Design Example: Assume that V IN = 10V, VOUT = 5V, IOUT = 1.5A, TA = 50°C, θHA = 1°C/W, θCH = 2°C/W, and θJC= 3C°/W, where: TA = ambient temperature, θHA = heatsink to ambient thermal resistance θCH = case to heatsink thermal resistance θJC = junction to case thermal resistance The power calculated under these conditions is: PD = (VIN – VOUT ) * IOUT = 7.5W.
