CMOS LDO Regulator Series for Portable Equipments
CMOS LDO Regulators
with Auto Power Saving Function
BH□□PB1WHFV Series
No.09020EAT05
Description
The BH□□PB1WHFV regulator series can respond to changes in output current by switching to a state in which regulator
characteristics are ideal. The regulators cut power consumption by lowering their own current consumption to approximately
2 A when the application is operating in the standby state. During normal-current operation it will automatically switch to
high-speed operating mode. The IC's soft start function reduce the rush current that flows to the output capacitors during
startup. The HVSOF5 package, which features excellent heat dissipation, contributes to space-saving application designs.
Features
1) Automatic switching between low-consumption and high-speed modes
2) Built-in rush current prevention circuit
3) Low-voltage 1.7 V operation
4) High accuracy output voltage: ± 1%
5) Circuit current during low-consumption operation: 2 A
6) Stable with a ceramic capacitor (0.47 F)
7) Built-in temperature and overcurrent protection circuits
8) Built-in output discharge during standby operation function
9) Ultra-small HVSOF5 power package

The IC incorporates a built-in auto power-saving function that
continuously monitors the output current and switches
automatically between a low current consumption regulator
and a high-speed operation regulator. This function reduces
the regulator's own current consumption to approximately 1/10
or lower of normal levels when the output current falls below
approximately 300 A.
To operate only the high-speed operation regulator without
using the auto power-saving function, fix the SEL pin to high.

Power Dissipation (Pd)
1. Power Dissipation (Pd)
Power dissipation calculations include estimates of power dissipation
characteristics and internal IC power consumption, and should be
treated as guidelines. In the event that the IC is used in an
environment where this power dissipation is exceeded, the attendant
rise in the junction temperature will trigger the thermal shutdown
circuit, reducing the current capacity and otherwise degrading the IC's
design performance. Allow for sufficient margins so that this power
dissipation is not exceeded during IC operation.

Input Output capacitors
It is recommended to insert bypass capacitors between input and GND pins, positioning them as close to the pins as
possible. These capacitors will be used when the power supply impedance increases or when long wiring paths are used, so
they should be checked once the IC has been mounted.
Ceramic capacitors generally have temperature and DC bias characteristics. When selecting ceramic capacitors, use X5R or
X7R, or better models that offer good temperature and DC bias characteristics and high tolerant voltages.

Output capacitors
Mounting input capacitor between input pin and GND(as close to pin as possible), and also output capacitor between output
pin and GND(as close to pin as possible) is recommended.
The input capacitor reduces the output impedance of the voltage supply source connected to the VCC. The higher value the
output capacitor goes, the more stable the whole operation becomes. This leads to high load transient response. Please
confirm the whole operation on actual application board.
Generally, ceramic capacitor has wide range of tolerance, temperature coefficient, and DC bias characteristic. And also its value goes
lower as time progresses. Please choose ceramic capacitors after obtaining more detailed data by asking capacitor makers.

Operation Notes
1. Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break
down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated
values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses.
2. Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
3. Inter-pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if pins are shorted together.
4.Thermal shutdown circuit (TSD)
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit is designed only to shut the
IC off to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. Do not continue to
use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is assumed.
5. Ground wiring patterns
The power supply and ground lines must be as short and thick as possible to reduce line impedance. Fluctuating voltage
on the power ground line may damage the device.

BH□□PB1WHFV Series
6. Overcurrent protection circuit
The IC incorporates a built-in overcurrent protection circuit that operates according to the output current capacity. This circuit
serves to protect the IC from damage when the load is shorted. The protection circuit is designed to limit current flow by not
latching in the event of a large and instantaneous current flow originating from a large capacitor or other component. These
protection circuits are effective in preventing damage due to sudden and unexpected accidents. However, the IC should not
be used in applications characterized by the continuous operation or transitioning of the protection circuits. At the time of
thermal designing, keep in mind that the current capability has negative characteristics to temperatures.
7. Actions in strong electromagnetic field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction.
8. Back Current
In applications where the IC may be exposed to back current flow, it is recommended to create a path to dissipate this
current by inserting a bypass diode between the VIN and VOUT pins.

Fig. 32 Example Bypass Diode Connection
9. I/O voltage difference
Using the IC in automatic switching mode when the I/O voltage differential becomes saturated (VIN - VOUT < 150 mV)
may result in a large output noise level. If the noise level becomes problematic, use the IC with the SEL pin in the high
state when the voltage differential is saturated.
10.GND Voltage
The potential of GND pin must be minimum potential in all operating conditions.
11. Preventing Rush Current
By attaching the Rss and Css time constants to the STBY pin, sudden rises in the regulator output voltage can be
prevented, dampening the flow of rush current to the output capacitors. The larger the time constant used, the greater the
resulting reduction. However, large time constants also result in longer startup times, so the constant should be selected
after considering the conditions in which the IC is to be used.

12. Regarding input Pin of the IC (Fig.34)
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated.
P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode
or transistor. For example, the relation between each potential is as follows:
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes
operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.
