The device is protected by several functional blocks. ADJ pin The Load output voltage feed-back comes from an external divider resistor bridge middle point connected to ADJ pin (allowing all possible output voltage settings as per User's desire) established between Load terminals. INHIBIT ON-OFF Control By setting INHIBIT pin TTL-High, the Device switches off the Output Current and Voltage. Device is ON when INHIBIT pin is set Low. Since INHIBIT pin is internally pulled down, it can be left floating in case Inhibit function is not utilized. Overtemperature protection A temperature detector internally monitors the power element junction temperature. The Device goes OFF when approx. 175C are reached, returning to ON mode when back to approx. 40C. Combined with other protection blocks, it protects the Device from destructive junction temperature excursions in all load conditions. It is worth noting that when internal temperature detector reaches 175C, the active power element can be at 225C: Extensive operation under these conditions far exceeds Maximum Operation Ratings and Device reliability cannot be granted. Overcurrent protection An internal non-fold back Short-Circuit limitation is set with ISHORT > 3.8A (VO is 0V). This value can be downwards modified by an external resistor connected between ISC pin and VI pin, with a typical value range of 10k to 200k. To keep excellent VO regulation, it is necessary to set ISHORT 1.6 times greater than the maximum desired application IO. When IO reaches ISHORT - 300mA, the current limiter overrules Regulation and VO starts to drop and OCM flag is risen. When no current limit adjustment is required, ISC pin must be left unbiased (as it is in 3pin packages). OCM pin Goes Low when current limit starts to be active, otherwise VOCM = VI. It is buffered and can sink 10mA. OCM pin is internally pulled-up by a 5 k resistor. Alternates to: RHFL4913 is recommended to replace all Industry Positive Regulators due to its exceptional Radiation performance. To replace 3-terminal Industry devices, use RHFL4913 Fixed Voltage versions. 5/10 RHFL4913 ADJUSTABLE VERSION APPLICATION INFORMATION Adjusting Output Voltage: R2 resistor must be connected between VO and ADJ. R1 resistor must be connected between ADJ and Ground. Resistor values can be derived from the following formula: VO = VADJ x (R1+ R2) / R1 VADJ is 1.22V, controlled by the internal temperature compensated Band Gap block. The minimum Output voltage is therefore 1.22V and minimum Input voltage is 3V. The RHFL4913 Adjustable is functional as soon as VI - VO voltage difference is slightly above the power element saturation voltage. The Adjust pin to Ground resistor must not be bigger than 10k to keep the output feed-back error below 0.2%. A minimum 0.5mA IO must be set to ensure perfect "no-load" regulation. It is advisable to dissipate this current into the divider bridge resistor. All available VI pins shall always be externally interconnected, same thing for all available VO pins, otherwise Device stability and reliability cannot be granted. The INHIBIT function switches off the output current in an electronic way, that is very quickly. According to Lenz's Law, external circuitry reacts with LdI/dt terms which can be of high amplitude in case somewhere an inductance exists. Large transient voltage would develop on both Device terminals. It is advisable to protect the Device with Schottky diodes preventing negative voltage excursions. In the worst case, a 14V Zener diode shall protect the Device Input. The Device has been designed for high stability and low drop out operation: Minimum 1F input and output tantalum capacitors are therefore mandatory. Capacitor ESR range is from 0.5 to over 20 . Such range turns out to be useful when ESR increases at low temperature. When large transient currents are expected, larger value capacitors are necessary. In case of high current operation with expected short-circuit events, caution must be considered relatively to capacitors. They must be connected as close as possible to device terminals. As some tantalum capacitors may permanently fail when submitted to high charge-up surge currents, it is recommended to decouple them with 470nF polyester capacitors. Being RHFL4913 Adjust manufactured with very high speed bipolar technology (6GHz fT transistors), the PCB layout must be performed with exceptional care, very low inductance, low mutually coupling lines, otherwise high frequency parasitic signals may be picked-up by the Device resulting into system self-oscillation. The benefit is an SVR performance extended to far higher frequencies. 6/10 RHFL4913 ADJUSTABLE VERSION SOC-14 MECHANICAL DATA DIM. mm. MIN. TYP inch MAX. MIN. TYP.
