Figure 2: Application Diagram For Remote Sensins Operation
DEVICE DESCRIPTION
The RHFL4913 Fixed Voltage contains a PNP type power element controlled by a signal resulting from
amplified comparison between the internal temperature compensated Band-Gap cell and the fraction of
the desired Output Voltage value. This fractional value is obtained from an internal-to-die resistor divider
bridge set by STMicroelectronics. The device is protected by several functional blocks.
Low pin count Package limitations
Some functions (INHIBIT, OCM, SENSE) are not available due to lack of pins. Corresponding die pads
are by default connected inside silicon.
SENSE pin
The Load voltage is applied by a Kelvin line connected to SENSE pin: Voltage feed-back comes from the
internal divider resistor bridge. Therefore possible output voltages are set by manufacturer mask metal
options. SENSE pin is not available in 3pin packages.
INHIBIT ON-OFF Control
By setting INHIBIT pin TTL-High, the Device switches off the Output Current and Voltage. The 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. INHIBIT pin is not available in 3pin packages.
Overtemperature protection
A temperature detector internally monitors the power element junction temperature. The Device goes
OFF at approx. 175°C, returning to ON mode when back to approx. 40°C. It is worth noting that when the
internal temperature detector reaches 175°C, the active power element can be at 225°C: Device reliability
cannot be granted in case of extensive operation under these conditions.
Overcurrent protection
I
pin. An internal non-fold back Short-Circuit limitation is set with I
> 3.8A (V is 0V). This value
SHORT O
SC
can be reduced by an external resistor connected between I pin and V pin, with a typical value range
SC
I
of 10kΩ to 200kΩ. This adjustment feature is not available in 3pin packages. To keep excellent V
O
regulation, it is necessary to set I
1.6 times greater than the maximum desired application I . When
SHORT
O
I
reaches I
– 300mA, the current limiter overrules Regulation and V starts to drop and the OCM
O
SHORT O
flag is risen. When no current limitation adjustment is required, I pin must be left unbiased (as it is in 3
SC
pin packages).
OCM pin
Goes Low when current limiter starts to be active, otherwise V
= V . It is bufferized and can sink 10mA.

OCM
OCM pin is internally pulled-up by a 5 kΩ resistor. Not available in 3pin packages.

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,
I
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 Ω to over 20 Ω.
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
T
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.
