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 cel l and the fraction of
the desired Output Voltage value. Th is fractional value is obtained from an in ternal-to-die resistor divider
bridge set by STMi croelectronics. The device is protected by several functional blocks.

Low pin co unt Package limitatio ns

Some functions (INHIBIT, OCM, SENSE) are not av ailab le due to lack of pins. Corresponding die pads
are by default connected inside s ilicon.

SENSE p in

The Load voltage is ap plied by a Kelvin line connected to SE N SE pin: Voltage feed-back comes from the
internal divider resistor bridge. Therefore possible outp ut voltages are set by manufacturer mask meta l
options. SENSE pin is not available in 3pin pac kages.

INHIBIT ON-OFF Control

By setting INHIBIT pin TTL-High, the Dev ice 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 m ode 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 grant ed in case of extensive operation under these conditions.

ensures perfect “no-load” regulation.

otherwise Dev ic e stability and reliability cannot be granted. A ll NC pins can be connect e d to Gr ound. The
INHIBIT function switches off the output current in an electronic way, that is very quickly. According to
Lenz’s Law, external c ircuitry 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 t he Dev ice with Schottky diodes preventing negat ive voltage
excursions. In the worst c as e, a 14V Zener diode shall protect the Device Input.
The Device has been designed for h igh stability and low drop out operation: Minim u m 1µF input and
output tantalum capacitors are therefore mand atory. Capacitor ES R range is from 0.5 Ω to over 20 Ω.
Such range turns out t o be useful when ESR increases at low temperature. When large transient currents
are expected, l arger v alue c apacitors are necessary.
In case of high c urrent operation with expected short-circuit events, cau tion must be consid ered relatively
to capac itors. They must be c onnected as close as possible to device terminals. As some tant alum
capacitors may permanently f ail when submitted to high charge-up surge currents, it is recommen ded to
decouple them wit h 470nF polyeste r capacitors.
Being RHFL4913 Fixed Voltage manufactured with very high speed bipolar technology 6GHz f
transistors), the PCB la y-ou t 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 cas e the Load is located far fro m the regulator, it is recommended to comply with the schem e below. To
obtain the best regulation, it is in addition essential to care about:

- The wire connecting R2 to the Load end mus t not be crossed by the Load current ( Kelvin sense).
The noise captured by the wires between the Load and the chip could brin g a noisy output voltage. In case
this happens, it is recommended that sh ielde d c ables are used for these co nnec ti ons . The external wrap
must be used for connect ing the ground of the chip with the Load Ground. It is a lso recommended to place
1uF tantalum c apacitors between Output and Ground close to the device and another nex t to the Load .
