RHFL4913 FIXED VERSION  
Alternate to  
RHFL4913 Fixed (& custom) Voltages replace all 3-terminal Industry Devices, providing essential benefits  
- Lower Drop-Out  
- High radiation performance  
- Better SVR  
- Saving the high stability external setting resistors.  
APPLICATION INFORMATION  
The RHFL4913 Fixed Voltage is functional as soon as V -V voltage difference is slightly above the power  
I
O
element saturation voltage. A minimum 0.5mA I ensures perfect “no-load” regulation.  
O
All available V pins must always be externally interconnected, same thing for all available V pins,

O
otherwise Device stability and reliability cannot be granted. All NC pins can be connected to Ground. 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 some  
series-inductance exists. The effect would be a large transient voltage developed on both Device  
terminals. It is necessary 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 1µF 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 Fixed Voltage manufactured with very high speed bipolar technology 6GHz f

transistors), the PCB lay-out must be performed with extreme care, very low inductance, low mutually  
coupling lines, otherwise high frequency parasitic signals may be picked-up by the Device resulting into  
self-oscillation. User’s benefit is a SVR performance extended to far higher frequencies.  
REMOTE SENSING OPERATION  
In case the Load is located far from the regulator, it is recommended to comply with the scheme below. To  
obtain the best regulation, it is in addition essential to care about:  
- The wire connecting R2 to the Load end must not be crossed by the Load current (Kelvin sense).  
The noise captured by the wires between the Load and the chip could bring a noisy output voltage. In case  
this happens, it is recommended that shielded cables are used for these connections. The external wrap  
must be used for connecting the ground of the chip with the Load Ground. It is also recommended to place  
1uF tantalum capacitors between Output and Ground close to the device and another next to the Load.
