Device description
The RHFL7913A adjustable contains a NPN-type power element controlled by signal
resulting from amplified comparison between internal temperature compensated band-gap
cell and the fraction of the desired output voltage value, generated by an external resistor
divider bridge. The NPN structure allows access to lower drop out levels because its base
current can be routed to ground pin and not to output. To control and monitor the device
from / to the external logic world – usually operating in positive voltage area – a dedicated
logic interface block (INHIBIT and OCM functions) has been implemented with +3 V to +5 V
supplied line V(+). In case V(+) = 0 V, inhibit and OCM functions are not available: In this
condition, INHIBIT function is ON and OCM pin is “no care”. The device is internally
protected by several blocks.
5.1
5.2
5.3
ADJ pin
The load voltage feedback comes from an external divider resistor bridge middle point to
ADJ pin established between load terminals.
Inhibit ON-OFF control
When INHIBIT pin is TTL-high (positive), the device switches off current and voltage
output. The device is ON when INHIBIT pin is set TTL-low.
Overtemperature protection
A temperature detector internally monitors power element junction temperature. The device
goes OFF ~165° - 175°C are reached, and returns ON when circa 100°C. When internal
temperature detector reaches 170°C, the active power element can be at 225 °C: Device
reliability cannot be granted during extensive operation duration with these conditions.
5.4
Overcurrent protection
ISC pin. An internal non-fold back short-circuit limitation is set with ISHORT > 4 A (VO is 0 V).
This value can be downward modified by an external resistor connected between ISC and VI
pins, with a typical value range of 10 kΩ to 200 kΩ. 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 – 300 mA, the current limitor overrules regulation and VO starts to drop and
OCM flag is risen. When no current limitation adjustment is required, ISC pin shall be left
unbiased (as it is in 3 pin packages).
5.5
5.6
OCM pin
Goes low when current limitor starts to be active, otherwise VOCM = V (+). It is bufferized
and can sink 10 mA. OCM pin is internally pulled-up by a 50 kΩ resistor. Can be left open
when V (+) = 0.
Alternates to
RHFL7913A is recommended to replace all industry negative regulators due to its
exceptional radiation performances. To replace 3-terminal industry devices, use
customized RHFL7913 fixed voltage versions.

RHFL7913A
Application information
6
Application information
Adjusting output voltage: R1 resistor must be connected between VO and ADJ pins. R2
resistor must be connected between ADJ and GND pins. Resistor values can be derived
from the following formula:
VO = VADJ (1 + R1/R2) with VADJ = -1.20 V
To access all RHFL7913A adjustable functionality, V (+) shall be set at 3.0 V (max 5 V). As
a consequence, VI (-) cannot be greater than –9.0 V (resp. –7 V) due to –12 V maximum
operation rating.
The device is functional as soon as VI - VO voltage difference is slightly above power
element saturation voltage. The adjustable pin to Ground resistor shall not be greater than
10 kΩ to make output feedback error be below 0.2%. A minimum 0.5 mA IO is necessary to
set to ensure perfect “no-load” regulation. It can be wise to dissipate this current into the
divider bridge resistor.
All available VI pins shall always be PCB interconnected, the same for all available VO pins,
otherwise device stability and reliability cannot be granted. The INHIBIT function switches
off output current in an electronic way, is very quickly. According to Lenz’ Law, external
circuitry reacts with –LdI/dt terms which can be of high amplitude in case some series-
inductance exists. Effect would be large transient voltage developed on both device
terminals. External Schottky diodes set on VI and VO may prevent voltage excursions
beyond max ratings. In the worst case, a 14 V Zener diode shall protect the device input. In
case of capacitive load, a input-output protection diode can be necessary to prevent VO to
be greater than VI during transient operation.
The device has been designed for high stability and low drop out operation: minimum 1 µF
input and output tantalum capacitors are therefore mandatory. Typical industry PCB design
practices 10 µF capacitors values are acceptable. Capacitor ESR range is from 0.020 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 shall be
considered relatively to capacitors. They shall be connected as close as possible form
device terminals. As some tantalum capacitors may permanently fail when submitted to
high charge-up surge currents, it is recommended to decouple them with 470 nF polyester
or ceramic capacitors.
RHFL7913A adjustable being manufactured with very high speed bipolar technology (6
GHz fT transistors), the PCB layout shall be performed with unprecedented 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. In difficult high current
circumstances (coming from PCB layout) a 470 nF polyester capacitor connected between
VO and ADJ pin increases stability margins. Benefit is SVR performances extended to far
higher frequencies.

6.1
Remote sensing operation
When load is physically far away from device output, the adjustable line can be set as a
kelvin sense line by implementing the divider resistor bridge as close as possible form
device, with a decoupling capacitor. The adjust pin kelvin sense line (to be not coupled with
power line) picks-up load voltage (load also locally decoupled with a capacitor). This layout
eliminates ohmic drop in load power wire. Similarly, by taking advantage of two separate
ground terminals: power ground pin shall be directly connected to load ground terminal
which is also the system ground, device signal ground shall be separately connected to
load ground terminal by another kelvin line: In this way, ground ohmic errors are minimized
because the only current flowing into device signal ground pin kelvin line is device Iq (a
matter of a few mA).
