Sorry for my English. It is not my native language.
I want to use ADM7155-04 with Vin = 3.2 - 4.2 V; Icc (max) = 100mA.
Vout = 3.3 V
In the datasheet on the chart I found the information about Vdropout = 60mV ( Vout=3.3V and Icc =100mA).
Will I be able to use this regulator at Vin= 3.2V to achieve Vout = 3.140 mV ( at Vout=3.3V with resistor devider).
I dont understand about Vreg = 3.6 V ( for ADM7155-04 in datasheet: Figure 42. Simplified Internal Block Diagram) and all the measurements are carried out at Vin = Vout(max) + 0.5V.
Table 10. Model Selection Guide for Input Voltage(in datasheet) indicates that for the ADM7155-04 Vout =1.2-3.4V at minimum Vin=3.9 V Icc=600 mA but on the first page datasheet Dropout voltage: 120 mV typical at VOUT = 3.3 V, IOUT = 600 mA
What do you think about it?
