Negative Input / Output Voltage LDO Regulator
1. Genaral Description
AP1156ADS series is a negative-input negative-output regulator IC using silicon monolithic bipolar structure
which can supply 150mA output current. The output voltage can be set from -1.3 to -1.5V, which is trimmed
in high accuracy. AP1156ADS is supplied with ON/OFF terminal and noise reduction terminal. The ON/OFF
control can be controlled directly with positive logic or CPU. The over current, thermal and reverse bias
protections are integrated.

11.7 ESR Stability
IC does operate with 1.0uF Cout. If it is 1.0uF or larger, the capacitor of any type can be used in all range
without considering ESR. But due to the parts are uneven, please enlarge the capacitance as much as possible.
With larger capacity, the output noise decreases more. In addition, the response to the load change, etc. can be
improved. The IC won’t be damaged by enlarging the capacity.
The input capacitor is necessary in case the battery voltage drops, the power supply impedance increases, or
the distance to the power supply is far. 1 input capacitor might be necessary for each 1 IC or for several ICs. It
depends on circuit condition. Please confirm the stability by each circuit.
Generally, Multi-layer ceramic capacitor (MLCC) has the temperature characteristic and the voltage
characteristic. Please select parts in consideration of the voltage and the temperature used.

The output can be seen as oscillated when the overheating protection or the overcurrent protection start
operation, or the input voltage is low. In this case, please lower the power consumption, decrease the load
current or make the input voltage higher.
Generally, a ceramic capacitor has the temperature characteristic and the voltage characteristic. Please select
parts in consideration of the voltage and the temperature used. ASAHI KASEI TOKO POWER DEVICES
recommend B characteristic type.

11.8 Operating Region and Power Dissipation
The power dissipation of the device is dependent on the junction temperature. Therefore, the package
dissipation is assumed to be an internal limitation. The package itself does not have enough heat radiation
characteristic due to the small size. Heat runs away by mounting IC on PCB. This value changes by the
material, copper pattern etc. of PCB.
The overheating protection operates when there is a lot of loss inside the regulator (Ambient temperature high,
heat radiation bad, etc.). The output current and the output voltage will drop when the protection circuit
operates. When joint temperature (Tj) reaches the set temperature, IC stops the operation. However, operation
begins at once when joint temperature (Tj) decreases.
・The thermal resistance when mounted on PCB
The chip joint temperature during operation is shown by Tj=θja×Pd+Ta. Joint part temperature (Tj) of
AP1156ADSxx is limited around 150°C with the overheating protection circuit. Pd is the value when the
overheating protection circuit starts operation. When you assume the ambient temperature to be 25°C,
150=θja×Pd(W)+25
θja×Pd=125
θja=125/Pd (°C/W)
・Example of mounting substrate
Figure 4. PCB Material: Two layer glass epoxy substrate
(x=30mm,y=30mm,t=1.0mm,Copper pattern thickness 35um)
Please do derating with 5.9mW/°C at Pd=736mW and 25°C or higher. Thermal resistance is (θja=170°C/W)
・Method of obtaining Pd easily
Connect output terminal to GND(short circuited), and measure the input current by increasing the input
voltage gradually up to 10V. The input current will reach the maximum output current, but will decrease soon
according to the chip temperature rising, and will finally enter the state of thermal equilibrium (natural air
cooling) The input current and the input voltage of this state will be used to calculate the Pd.
Pd(mW)  Vin (V)  Iin (mA)
When the device is mounted, mostly achieve 600mW or more.
Pd(mW)
Procedure (When mounted on PCB).
1.Find Pd (Vin×Iin when the output is short-circuited).
2. Plot Pd against 25°C.
3. Connect Pd to the point corresponding to the 150°C with a
straight line.
4. Pull a vertical line from the maximum operating
temperature in your design (e.g., 75°C).
5. Read the value of Pd against the point at which the
vertical line intersects the derating curve(DPd).

The maximum output current at the highest operating temperature will be Iout≒DPd÷(Vinmax-Vout).
Please use the device at low temperature with better radiation. The lower temperature provides better quality.
・The operation area
Pd when mounted on the substrate as shown on the Figure 4. (Ta=25°C)
SOT23-5=736mW (derating –5.9mW)
The current which can be used continuously with Ta=25°C min is calculated by the following.
Iout (mA) 
736  5.9  (Ta  25)
… SOT23-5
Vin  Vout
*Iout<150mA
The operation area is the part enclosed in the line including the “0” mentioned in graph1
The overheating sensor may operate, or the output voltage may drop outside those area.
The heat radiation characteristic changes in various conditions, so please check under your condition.

12. Definition of term
■Relating Characteristic
Each characteristic will be measured in a short period not to be influenced by joint temperature (Tj).
・Output voltage (Vout)
The output voltage is specified with Vin= Vout(typ)+1V and Iout=5mA
・Output current (Iout)
Output current, which can be used continuously (It is the range where overheating protection of the IC does not
operate.)
・Peak output current (IoutPEAK)
The rated output current is specified under the condition where the output voltage drops 90% by increasing the
output current, compared to the value specified at Vin=Vout(typ)-1.5V.
・Dropout voltage (Vdrop)
It is an I/O voltage difference when the circuit stops the stable operation by decreasing the input voltage.
It is measured when the output voltage drops 100mV from its nominal value by decreasing the input voltage
gradually.
・Line Regulation (LinReg)
It is the fluctuations of the output voltage value when the input voltage is changed.
・Load Regulation (LoaReg)
It is the fluctuations of output voltage value when the input voltage is assumed to be Vout(typ) -1.5V, and the
load current is changed.
・Ripple Rejection (R.R)
Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output.
It is measured with the condition of
Vin=Vout-2.0V. Ripple rejection is the ratio of the ripple content
between the output vs. input and is expressed in dB
・Standby current (Istandby)
It is an input current which flows to the Cont terminal, when the IC is turned off.
■Relating Protection Circuit
・Over Current Protection
It is a function to protect the IC by limiting the output current when excessive current flows to IC, such as the
output is connected to GND, etc.
・Thermal Protection
It protects the IC not to exceed the permissible power consumption of the package in case of large power loss
inside the regulator.
The output is turned off when the chip reaches around 150℃, but it turns on again when the temperature of the
chip decreases.
